ABSTRACT:
A pressure sensor apparatus sealed by a resin in which resin flash in the resin sealing process is prevented from occurring, eliminating the necessity of removing such flash and achieving a pressure sensor apparatus which may be manufactured relatively easily at a lower price and with a higher reliability. A semiconductor pressure sensing element is mounted on a stem and signals lines for outputting an electrical signal indicating a pressure detected extend through the stem. An annular stopper for preventing resin flash resulting from the sealing resin flowing to an unwanted location surrounds both the semiconductor pressure sensing element and the signal lines.
