1. A laminated coil component comprising:
an element body including a first face and a second face opposed to each other in a first direction, a third face and a fourth face opposed to each other in a second direction orthogonal to the first direction, and a fifth face and a sixth face opposed to each other in a third direction orthogonal to the first direction and the second direction;
a coil including a plurality of coil conductors in the element body, wherein an axis of the coil is along the third direction; and
a first conductor and a second conductor disposed on the element body and spaced apart from each other in the first direction, wherein
the first conductor includes a first conductor portion extending in the first direction and a second conductor portion extending in the second direction,
a first depression is disposed on the third face, and the first conductor portion is disposed in the first depression,
a second depression is disposed on the first face, and the second conductor portion is disposed in the second depression and spaced apart from the fourth face,
the second conductor includes a third conductor portion extending in the first direction and a fourth conductor portion extending in the second direction,
a third depression is disposed on the third face, and the third conductor portion is disposed in the third depression,
a fourth depression is disposed on the second face, and the fourth conductor portion is disposed in the fourth depression and spaced apart from the fourth face,
the coil includes a first coil portion and a second coil portion when viewed from the third direction,
the first coil portion is disposed closer to the fourth face than an end portion of the second conductor portion at a side of the fourth face in the second direction,
the second coil portion is disposed closer to the third face than the end portion in the second direction,
a shortest distance between the second coil portion and the first face in the first direction and a shortest distance between the second coil portion and the second face in the first direction both increase from the fourth face toward the third face,
the second coil portion includes a curved portion in a first region when viewed from the third direction, the first region being located between the first conductor and second conductor when viewed from the second direction, and
wherein the first coil portion is spaced apart from the second conductor portion and the fourth conductor portion in the first direction when viewed from the second direction.
