A method and device for producing an absolute pressure-type pressure sensor, the method and device enabling a relative pressure-type pressure sensor to be modified (converted) into the absolute pressure-type pressure sensor in a simple and easy way. The method is characterized by having a step of placing a relative pressure type pressure sensor in a vacuum chamber, the relative pressure type pressure sensor having inside a reference pressure chamber and having a pressure guide hole whose one end communicates with the reference pressure chamber and the other end opened upward to the atmosphere, the relative pressure type pressure sensor being placed in the vacuum chamber such that the other end of the pressure guide hole opens upward; a step of placing a solder on the other end of the pressure guide hole, a step of drawing vacuum from the vacuum chamber; and a step of heating the solder until it melts. |
