Abstract: A coil device has a wound portion, a leadout portion led out from the wound portion, a terminal including a wire connecting portion connected to the leadout portion, and an element body covering the wound portion, the leadout portion and the wire connecting portion. A winding axis of the wound portion is perpendicular to a mounting facing surface of the element body. The leadout portion has a bent portion bent so as to protrude inward when viewed along the winding axis, and an inner angle of the bent portion is an obtuse angle.

Abstract: An inductor 1 includes a coil 2 made of a flat wire, a terminal 4a including a wire connecting portion 42a connected to a lead portion 3a of the coil 2, a terminal 4b including a wire connecting portion 42b connected to a lead portion 3b of the coil 2, and a core 8 that covers the coil 2 together with the wire connecting portion 42a and the wire connecting portion 42b. The wire connecting portion 42a is positioned outside the lead portion 3a that is led out in a front-rear direction of the core 8, along a left-right direction of the core 8. The wire connecting portion 42b is positioned outside the lead portion 3b that is led out in the front-rear direction of the core 8, along the left-right direction of the core 8.
