Beschreibung
Zusammenfassung:	A less expensive small semiconductor pressure sensor in which a pressure sensing element is not displaced by vibration and the like and wire bonding is highly reliably effected includes a pressure sensing element having a diaphragm and a glass base die bonded to a die pad in substantially the same plane as that of an outer lead with a bonding resin. Each of two sets of hanging leads is attached to one of two opposite sides of the die pad to fix the die pad to a package base. With this arrangement, the die pad is securely bonded to the package base to prevent breakage of a metal wire caused by vibration and the like so that a less expensive and smaller semiconductor pressure sensor can be provided.
