A push-in type semiconductor chip has a semiconductor device, a support electrode body bonded to one of the end portions of the semiconductor chip and supported by, and fixed to, a heat spreader at a support fixing portion thereof, a lead electrode body bonded to the other end portion of the semiconductor chip and an insulating/sealing member disposed at the bond portion between the semiconductor chip and the support electrode body and at the bond portion between the semiconductor chip and the lead electrode body. The support electrode body includes a first portion having an outer diameter different from that of the support fixing portion at which the support electrode body is supported and fixed by the heat spreader. By setting a predetermined relationship between the outer diameters of the first portion and the support fixing portion, deformation and breakage of the semiconductor chip during assembly can be prevented.
