Classification: CPC H | IPC H

Claim 7:
8. A semiconductor device, comprising:
a conductive board;
a contact component having a cylindrical through hole therein, and including a main body portion with a first open end and a second open end opposite to each other in an insertion direction, the main body portion having a flange provided at at least the first open end, the first open end being joined to the conductive board; and
an external connection terminal having a plurality of outer surfaces extending in an insertion direction to form a prism shape, and being inserted into the through hole of the contact component, the external connection terminal having corner portions along the insertion direction pressed by an inner circumferential surface of the through hole, wherein
the main body portion of the contact component has a ring-shaped reinforcing portion on an outer circumferential surface of the main body portion, the reinforcing portion flaring outward in a direction orthogonal to the outer circumferential surface, and being provided along a circumferential direction of the main body portion at at least one of the first open end or the second open end on the outer circumferential surface of the main body portion.
