Zusammenfassung:To provide a connection terminal for a power module, which can maintain an excellent contact state stably. A connection terminal 3 is a part of a power module including a semiconductor element, a substrate on which the semiconductor element is mounted, and a tubular conductive holding member which is joined to a surface of the substrate, and extends in a direction perpendicular to the surface. The connection terminal 3 electrically connects an external circuit to the substrate all the time by being held by the holding member. A conductive wire is wound in the connection terminal 3. The connection terminal 3 includes an insertion part 31, at least a part of which is closely wound and inserted into a hollow part of the holding member, a rough winding part 32 in which the wire is wound at a predetermined interval, and a contact part 34 which is provided at an end part of the rough winding part 32 on a side different from the end part on a side of the insertion part 31, and comes into contact with the external circuit. The insertion part 31 includes a press-fitting part having a diameter larger than that of the hollow part.
