This conductor apparatus mounts through a bump a semiconductor chip having an electrode pad on a circuit board having a connection pad at a position opposite to the electrode pad. The bump comprises a first protruding electrode provided on the electrode pad, a second protruding electrode provided on the connection pad, and an electroconductive connection member which integrally covers peripheral surfaces of the first and second protruding electrodes and solid-phase-diffusion-connects these protruding electrodes.
