More Information
Summary:An inductor component comprising a spiral wiring wound on a plane; first and second magnetic layers located at positions sandwiching the spiral wiring from both sides in a normal direction relative to the plane of the wound spiral wiring; a vertical wiring extending from the spiral wiring in the normal direction to penetrate at least the inside of the first magnetic layer; and an external terminal disposed on at least a surface of the first magnetic layer to cover an end surface of the vertical wiring. The first magnetic layer is larger than the second magnetic layer in terms of the area of the external terminal viewed in the normal direction, and when A is the thickness of the first magnetic layer and B is the thickness of the second magnetic layer, A/((A+B)/2) is from 0.6 to 1.6.
