Abstract: An inductor component 1a includes a resin layer 3 and an inductor electrode 6. The inductor electrode 6 includes metal pins 7a to 7d that extend in the resin layer 3 with upper end surfaces thereof exposed from the upper surface 3a of the resin layer 3, and upper wiring plates 8a and 8b that are disposed on the upper surface 3a of the resin layer 3 and that connect upper end surfaces of the short metal pins 7a and 7c and upper end surfaces of the long metal pins 7b and 7d to each other. In this case, the inductor electrode 6 is formed of the metal pins 7a to 7d and wiring plates 8a to 8c that each have a specific electrical resistance lower than that of a conductive paste and plating, and the resistance of the entire inductor electrode 6 can be decreased.
