A piezoresistive pressure sensor is provided, which can prevent the occurrence of ESD breakdown due to the nearness of interconnection layers of a resistive element according to miniaturization thereof. The piezoresistive pressure sensor is so configured that respective semiconductor resistive layers on both sides of an arrangement are formed to be relatively longer than an adjacent semiconductor resistive layer, and thus a corner portion of a semiconductor connection layer that extends from the respective semiconductor resistive layers on both sides of the arrangement and a corner portion of the semiconductor interconnection layer that is nearest to the corner portion of the semiconductor connection layer, between which the ESD breakdown occurs easily, can be separated from each other. |
