PROBLEM TO BE SOLVED: To prevent gel from extending into a bonding section in a pressure sensor in which a port is bonded on a case where the gel covers a pressure detecting section. SOLUTION: The gel 1 can be prevented from extending into the bonding section 2 by disposing a groove 8 with a V-shaped cross-sectional form on the case 6 and between the bonding section 2 and a recessed section 11, even in the case that the gel 1 is poured into the recessed section 11, and then the gel rises along a wall of the recessed section 11 and flows out from the recessed section 11. Accordingly, the adhesive quality between the case 6 and the port 5 is improved in the bonding section 2, and the airtight property for outside can be ensured.
