A pad on a semiconductor chip is connected to a solder ball, which communicates with an external circuit, without using a lead, thereby increasing the degree of freedom of bonding, and miniaturizing the semiconductor device. An insulative shaft provided with conductive parts on its surface is attached to the semiconductor chip generally parallel to the surface of the chip. The pad on the chip is connected to the conductove part of the insulator shaft via a bonding wire, and the solder ball is joined to the conductive part.
