PURPOSE:To realize connections high in their density and in their reliability by burying a plurality of metallic members into an insulator and exposing both ends of the metallic members so as to compose an electrical connection member and next interposing this electrical connection member between both electrical circuit components and next alloying parts where the exposed metallic members are connected to both the circuit components and connecting their connection parts. CONSTITUTION:An electrical connection member 125 is used to be connected to respective connection parts 102, 105 of circuit substrates 101, 104 as described in the following. The member 125 is composed by burying a plurality of metallic members, made of metal or alloy, into an insulator 111. The members 107 are exposed on both their ends, and they are interposed between the substrates 101 and 102 so that they are made in contact with the connection parts 102 and 105. The connection parts 102 and ends 108 of the members 107 on one side are alloyed to be connected to each other, and so are the connection parts 105 and ends 109 of the members on the other side. According to this method, connections high in their density and in their reliability can be realized between a semiconductor element and parts such as a circuit substrate, a lead frame, or the like.
