A semiconductor device is arranged such that a semiconductor chip having electrodes is flip chip mounted on printed substrate pads on a printed wiring substrate by a bump formed on each electrode. The semiconductor chip and the printed wiring substrate are fixed with a thermo-setting resin. A penetration hole is formed within an area where the printed substrate pad contacts each gold bump, and the gold bump has a joint section also on a side face of the penetration hole of the printed substrate pad. With this structure, the semiconductor device has a secure electrical connection between the bump and the metal pattern.
