[ 6. A lamination inductor comprising:
a component main-body formed in a substantially rectangular parallelepiped shape including a lower surface, a first end surface and a second end surface, wherein the first and second end surfaces oppose each other and are each connected to the lower surface and wherein the component main-body has a lamination structure in which a plurality of insulator layers are laminated together;
a coil conductor disposed inside the component main-body, wherein the coil conductor extends helically by alternately connecting a plurality of loop conductor layers and a plurality of via hole conductors, wherein one of the plurality of loop conductor layers extends more than one turn in a spiral form; and
a first outer terminal electrode electrically connected to a first end of the coil conductor and a second outer terminal electrode electrically connected to a second end of the coil conductor;
wherein a first portion of the first outer terminal electrode is embedded in the component main-body and a second portion of the first outer terminal electrode forms a first exposed surface that extends in a substantially L-shaped form and is exposed from a portion of the first end surface and from a portion of the lower surface,
wherein a first portion of the second outer terminal electrode is embedded in the component main-body and a second portion of the second outer terminal electrode forms a second exposed surface that extends in a substantially L-shaped form and is exposed from a portion of the second end surface and from a portion of the lower surface,
wherein the first outer terminal electrode and the second outer terminal electrode are separated from each other by a gap,
wherein the plurality of the loop conductor layers collectively includes a lower side portion extended along the lower surface,
wherein at least one of the plurality of the loop conductor layers includes: a first lateral side portion extended along the first end surface, and a first oblique side portion connecting a first end portion of the lower side portion to a first end portion of the first lateral side portion, the first oblique side portion oriented in a first oblique direction relative to the lower surface,
wherein the lower side portion is positioned within a range of the gap and has a length shorter than the gap,
wherein inner edges of the first lateral side portion do not overlap with an imaginary line connecting the first outer terminal electrode and the second outer terminal electrode in a direction parallel to the lower surface, and
wherein, for each loop conductor layer of the plurality of loop conductor layers, in a view normal to a plane containing the loop conductor layer:
in a portion of the first exposed surface that extends in a direction of the first end surface, a first location that is farthest from the lower surface defines a first point,
in a portion of the first exposed surface that extends in a direction of the lower surface, a second location that is farthest from the first end surface defines a second point,
a first imaginary line contains the first point and the second point, and
the first imaginary line does not intersect the coil conductor. ]
