A method of manufacturing a semiconductor device prepares contact members, each of which has a cylindrical through-hole, and column-shaped connection terminals, each having a polygonal shape in a cross-sectional view along a length direction thereof, wherein a length of a diagonal of the polygonal shape is greater than an inner diameter of the through-holes. Chamfers with a curvature for fitting an inner surface of the through-holes are formed at corners of the connection terminal, and the connection terminals are press-fitted into the through-holes of the contacts. By doing so, the area of contact where the connection terminals press-fitted into the contacts contact the inner circumferential surfaces of the through-holes of the contacts is increased. This increases the tensile load of the connection terminals fitted into the contacts.
