Abstract:
1. A pressure sensor comprising: a sensor chip for outputting an electric signals in accordance with a pressure received at a pressure receiving surface formed on a one surface of the sensor chip; a first case having one end portion at which the sensor chip is provided; a second case attached to the one end portion of the first case to cover the sensor chip, wherein the second case is provided with a pressure introducing passage for introducing the pressure to the sensor chip; a wiring board provided at the one end portion of the first case to have a surface facing toward the pressure introducing passage; a plurality of bumps through which the sensor chip is electrically connected with the surface of the wiring board by a flip-chip bonding such that the pressure receiving surface faces the surface of the wiring board; and an insulating member having an electrically insulating property, which seals a connection portion of the bumps.
