Summary:The invention provides an inductor component which can reduce deviation of inductance value even if the inductor component is thinned. The inductor component includes: a spiral wiring wound on a plane; a first magnetic layer and a second magnetic layer that are positioned so as to sandwich the spiral wiring from both sides in the normal direction with respect to the plane around which the spiral wiring is wound; a vertical wiring extending from the spiral wiring in the normal direction and penetrating through the inside of at least the first magnetic layer among the first magnetic layer and the second magnetic layer; and an external terminal penetrating at least inside the first magnetic layer and covering an end surface of the vertical wiring exposed from a surface thereof. The surface area of the external terminal of the first magnetic layer is larger than that of the second magnetic layer, and when the thickness of the first magnetic layer is A and the thickness of the second magnetic layer is B, A/((A + B
