PROBLEM TO BE SOLVED: To provide a pressure sensor high in degree of freedom in designing while keeping the joining strength of a seal diaphragm, and a method of manufacturing the same. SOLUTION: The method of manufacturing the pressure sensor is a method for assembling a connector housing fixed with a pressure sensing element and a sensor housing 40 with a laser welded seal diaphragm 50. This manufacturing method is composed of a process for producing a sensor housing, and a process for laser irradiation. The sensor housing producing process is that the sensor housing 40 has a seating part 401 for joining an outer periphery plane 501 of the seal diaphragm 50, and on the seating part 401 a metal layer 402 of different material from the seating part 401 is provided for forming a joining surface 458. The laser irradiation process is that on a joining surface 458 of the sensor housing 40 produced in the sensor housing producing process, the outer periphery plane 501 of the seal diaphragm 50 is abutted and irradiated with the laser.
