Claims

[Claims for Utility Model Registration] A cylindrical housing containing a semiconductor pressure conversion element and a plurality of housings connected to input/output terminals of the semiconductor pressure conversion element to perform temperature compensation, input/output level adjustment, etc. of the semiconductor pressure conversion element. In the pressure sensing device, the printed circuit board is formed of a flexible material and is rolled into a cylindrical shape having approximately the same diameter as or smaller than the side surface of the housing. A pressure detection device characterized in that the components are mounted in an internal space formed by the printed circuit board or on an external peripheral surface.
