Abstract: An inductor component includes an inductor electrode having two metal pins that form input and output terminals and a connecting conductor that connects one end of each of the metal pins to each other, the inductor electrode arranged such that other ends of the metal pins oppose each other, and a resin layer containing the inductor electrode such that other ends of the metal pins are exposed. The resin layer is formed having a single-layer structure. Variation in the characteristics of the inductor electrode can be reduced as compared to a case where the parts corresponding to the metal pins of the inductor electrode are formed as via conductors or through-hole conductors. Because the resin layer has a single-layer structure, stress acting on joint portions between the metal pins and the connecting conductor can be reduced, which makes it possible to improve the reliability of the inductor component.

Abstract: A small-sized inductor with desired characteristics is provided. An inductor 1a includes a resin layer 3 and an inductor electrode 6, which includes an inner winding portion 6a and an outer winding portion 6b. The inner winding portion 6a and the outer winding portion 6b forming the inductor electrode 6 include the metal pins 7a to 7d and the wiring boards 8a to 8d. Here, the inner winding portion 6a and the outer winding portion 6b include the metal pins 7a to 7d and the wiring boards 8a to 8d, which have lower specific resistance than conductive paste or plating. This structure thus can reduce the resistance of the entirety of the inductor electrode 6, and improve the characteristics of the inductor 1a. The inductor 1a can reduce its size by including the inductor electrode 6 wound to have a multiplex winding structure.

Abstract: A first resin layer (resin insulating layer) is formed by forming first and third covering portions in close contact with peripheral surfaces of respective end portions of first and second metal pins on the side closer to first end surfaces thereof, and by forming a body portion in a state of covering the respective surfaces of the first and third covering portions. Therefore, even when the first resin layer is thermally contracted, boundary regions of the one principal surface of the first resin layer around the respective end portions of the first and second metal pins on the side closer to the first end surfaces are filled with the first and third covering portions. Hence gaps can be prevented from being generated in those boundary regions, and a columnar conductor (first metal pin) can be avoided from deviating in position.
