PROBLEM TO BE SOLVED: To inhibit air bubbles from being produced in a protection member when the protection member is hardened, in the case of a manufacturing method of a pressure sensor wherein a sensor chip for pressure detection is mounted in a resin case with a pin as a conductor member insert-molded therein and the sensor chip and pin are covered/protected by a thermohardening protection member. SOLUTION: The sensor chip 20 is mounted in the resin case 10. The sensor chip 20 is wire-bonded to the pin 30. Then, the protection member 50 is packed into the case 10, and thus the pin 30 and sensor chip 20 are covered by the protection member 50. Then, the protection member 50 is thermally hardened while being pressurized from outside.
