Claim 0:
1. 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 orthogonal to a surface of the conductive board, the contact component at the first open end being joined to the conductive board; and
an external connection terminal having four outer surfaces extending in the insertion direction to form a quadrangular prism shape, and being inserted into the through hole of the contact component in the insertion direction, the external connection terminal having four corner portions along the insertion direction pressed by an inner circumferential surface of the through hole of the contact component, wherein
the external connection terminal has protrusions, each of which is disposed on a respective one of at least one pair of opposite outer surfaces among the four outer surfaces, and being pressed by the inner circumferential surface of the through hole.
