摘要： There is provided a method and device for producing an absolute pressure type pressure sensor that enables a relative pressure type pressure sensor to be modified (converted) into an absolute pressure type pressure sensor in a simple and easy manner. The method is characterized by comprising: a step of arranging a relative pressure type pressure sensor, that has a reference pressure chamber therein, and a pressure guide hole whose one end communicates with the reference pressure chamber and the other end opens to the atmosphere, inside a vacuum chamber with the other end of the pressure guide hole opening upward; a step of placing a solder piece onto the other end of the pressure guide hole; a step of drawing a vacuum inside the vacuum chamber; and a step of heating the solder piece until the solder melts.
