1. A reactor, comprising:
a coil including a pair of winding portions arranged in parallel;
a magnetic core to be arranged inside and outside the winding portions;
a holding member for specifying mutual positions of the coil and the magnetic core;
a case for accommodating an assembly including the coil, the magnetic core and the holding member; and
a sealing resin portion to be filled into the case,
wherein:
the case includes a bottom plate portion, the assembly being placed on the bottom plate portion, a side wall portion in the form of a rectangular tube for surrounding the assembly, and an opening facing the bottom plate portion,
the side wall portion includes a pair of long side parts facing each other and a pair of short side parts facing each other,
the assembly is so accommodated into the case that an axial direction of each winding portion is along a depth direction of the case,
the magnetic core includes an outer core portion to be arranged outside the winding portions and on the opening side,
the holding member includes an outer wall portion for covering at least a part of an outer peripheral surface of the outer core portion and a protruding portion projecting from the outer wall portion toward one of the short side parts, and
a clearance is provided between at least one of the long side parts and the protruding portion when the case is viewed from above.
