  • Patent number: 10151656
    Abstract: A pressure sensor includes a pressure sensor element, a joint provided to a target member, and an attachment member that is fitted into the joint through the connection section and connected to the target member. Each of the pressure sensor element and the joint is formed of a material that is not embrittled upon being in contact with a fluid to be measured that embrittles a material, and more rigid than the attachment member. The connection section is subjected to a plastic deformation connection (metal flow). An expensive hydrogen embrittlement resistant material is used for the pressure sensor element and the joint that are brought into contact with the fluid to be measured, and an inexpensive material is used for the attachment member that is not brought into contact with the fluid to be measured, thereby reducing the production cost of the pressure sensor.
