Claim:
1. A method for manufacturing a pressure sensor comprising: preparing a stem which has a cylindrical shape with a bottom having a hollow portion with an opening on one end of the stem, the bottom as a diaphragm being deformable by a pressure introduced into the hollow portion; mounting a sensor chip, which outputs a sensor signal according to a deformation of the diaphragm, on a side of the diaphragm opposite to the hollow portion; preparing a conductive member, in which an internal connection region connected to the sensor chip through a first connection member is integrated with an external connection region electrically connected to an external circuit by an outer frame; forming a first resin mold by molding with mold resin to couple the internal connection region to the external connection region; separating the outer frame from the internal connection region and the external connection region; arranging the internal connection region of the conductive member in the stem; and electrically connecting the sensor chip and the internal connection region through the first connection member, the conductive member further includes a mounting region between the internal connection region and the external connection region, the method for manufacturing the pressure sensor further comprising: mounting a circuit element for performing a predetermined process on the mounting region before the arranging of the internal connection region; electrically connecting the circuit element and the internal connection region through a second connection member; and electrically connecting the circuit element and the external connection region through a third connection member, wherein: in the forming of the first resin mold, the first resin mold seals the mounting region, the circuit element, the second connection member, and the third connection member.
