  • Pressure sensor
    Patent number: 11137307
    Abstract: A sensor chip (24) is joined to an inner wall surface (20a) of a base body (21-1), with a lower surface (24a) of a first retaining member (24-2) serving as a joint surface, in such a manner as to allow an enclosing chamber (23) (including a pressure receiving chamber (23-1) and a pressure guiding passage (23-2)) between a pressure receiving diaphragm (22) and the joint surface (24a) of the sensor chip (24) to communicate with a pressure guiding hole (24-2b) in the first retaining member (24-2). In this state, a narrow tube (31) made of stainless steel is passed through the pressure guiding passage (23-2) in the base body (21-1) and inserted and secured in the pressure guiding hole (24-2b) in the first retaining member (24-2).
