    • A pressure detecting device includes a semiconductor substrate (30, 200, 300, 400) for outputting an electrical signal corresponding to an applied pressure received from a pressure transmitting member (20) having electrically conductive properties disposed on the front surface of the semiconductor substrate (30, 200, 300, 400). The substrate (30, 200, 300, 400) and the pressure transmitting member (20) are accommodated in a housing (10). A lead member (50) electrically independent of the housing (10) is accommodated in the housing (10) at the back surface side of the semiconductor substrate (30, 200, 300, 400), and the lead member (50) and an electrode (35b) of the substrate (30, 200, 300, 400) are electrically connected to each other through conductive adhesive material (40). The housing (10) preferably includes a first portion (101), a second portion (102) having smaller thermal conductivity than the first portion, and an electrically conductive partition portion (103).
    • 压力检测装置包括半导体衬底(30,200,300,400),用于输出对应于从具有设置在半导体衬底的前表面上的导电性能的压力传递部件(20)接收的施加的压力的电信号( 30,200,300,400)。 衬底(30,200,300,400)和压力传递构件(20)容纳在壳体(10)中。 电气独立于壳体(10)的引线构件(50)在半导体衬底(30,200,300,400)的背面侧容纳在壳体(10)中,并且引线构件(50)和 基板(30,200,300,400)的电极(35b)通过导电粘合材料(40)彼此电连接。 壳体(10)优选地包括第一部分(101),具有比第一部分更小的热导率的第二部分(102)和导电分隔部分(103)。
