A pressure sensor is disclosed. The pressure sensor comprises a sensor chip having a depressed portion and a diaphragm defining a bottom of the depressed portion, a support member defining a pressure transmission passage communicating with the depressed portion, and a gel member continuously filling the depressed portion and at least a part of the pressure transmission passage. The sensor chip is bonded to a mounting surface of the support member with an adhesive. An edge of an open end of the pressure transmission passage on the mounting surface faces an surrounding region of the depressed portion of the sensor chip. |
