Summary:PROBLEM TO BE SOLVED: To provide an inductor element that is constituted to easily change its inductance. SOLUTION: This inductor element is provided with bonding pads 14-30, arranged on a printed wiring board 12 in a matrix form, pattern arms 36-46 which respectively form wiring patterns 48-52 in one direction, by connecting bonding pads arranged in the direction to each other, and bonding wires 54-58 which bond arbitrary bonding pads constituting adjacent wiring patterns to each other. The inductance value of the inductor element can be adjusted, by changing at least one of the lengths of the bonding wires 54-58, the lengths of the wiring patterns 48-52, and the number of the wiring patterns 48-52 by selecting desired bonding pads from the bonding pads 14-30 constituting the wiring patterns.
