PRESSURE SENSOR

PROBLEM TO BE SOLVED: To provide a pressure sensor capable of dispense with covering a connection portion between a first terminal and a second terminal with a protection member sealing and protecting a connection portion between the first terminal and a pressure detection element.SOLUTION: A port portion 90 includes a seal portion 93 partitioning a chamber 110 into a first space 110a communicating with a pressure introduction space 92 and a second space 110b separate from the first space 110a and hermetically sealed. A pressure detection element 20 is disposed in the first space 110a, and a connecting portion connecting a first terminal 13 to a second terminal 84 is disposed in the second space 110b so as to be either exposed or sealed by a protection member lower in corrosion resistance than a protection member 70 sealing and protecting a connecting portion connecting the first terminal 13 to the pressure detection element 20.SELECTED DRAWING: Figure 1 【課題】第１ターミナルと第２ターミナルとの接続部分を第１ターミナルと圧力検出素子との接続部分を封止して保護する保護部材で覆わなくてもよい圧力センサを提供する。【解決手段】ポート部９０に、部屋１１０を、圧力導入空間９２と連通される第１空間１１０ａと、第１空間１１０ａと分離されて密閉された第２空間１１０ｂとに区画するシール部９３を備える。そして、圧力検出素子２０を第１空間１１０ａに配置し、第１ターミナル１３と第２ターミナル８４との接続部分を第２空間１１０ｂに配置して露出するか、または、第１ターミナル１３と圧力検出素子２０との接続部分を封止して保護する保護部材７０より耐腐食性が低い保護部材で封止する。【選択図】図１
