ABSTRACT:
In a manufacturing method of a pressure detector, a first member that includes a sensing portion for outputting an electric signal in accordance with a pressure, a second member that includes a pressure-receiving diaphragm, and a pressure transmission member are prepared. The pressure transmission member is disposed between the sensing portion and the pressure-receiving diaphragm and the first member and the second member are welded in a state where the pressure is applied from the pressure-receiving diaphragm to the sensing portion through the pressure transmission member. One of the first member and the second member are strained so that a preliminary load, which is applied from the pressure-receiving diaphragm to the sensing portion through the pressure transmission member in a state where no external pressure is applied to the pressure-receiving diaphragm, meets a predetermined value.
