PRESSURE SENSOR

Provided is a pressure sensor that is compact, ensures insulation, and is highly reliable. A pressure sensor (1) comprises: a sensor body (2); a pressure sensor element (21) provided on one surface side of the sensor body (2); a through hole (24) which is formed from the one surface side of the sensor body (2) toward another surface side of the sensor body, and through which a lead wire (3) electrically connected to the pressure sensor element (21) is passed; and an insulation layer (24a) formed in the inner wall of the through hole (24). Passed through the through hole (24) is a conducting body core part (32), which is a part of the lead wire (3) from which an insulation coating has been removed. 本发明提供一种压力传感器，其为小型，且确保绝缘性而可靠性高。压力传感器(1)包括：传感器本体(2)；压力传感器元件(21)，设于所述传感器本体(2)的一面侧；贯穿孔(24)，从所述传感器本体(2)的一面侧向另一面侧形成，供电连接于所述压力传感器元件(21)的导线(3)穿过；以及绝缘层(24a)，形成于所述贯穿孔(24)的内壁。在贯穿孔(24)中，导线(3)的绝缘被覆经除去的导体芯线部(32)穿过。
