A pressure sensor includes: a housing having a pressure introduction port; and a connector case integrated with the housing. The connector case includes: a protruding portion that protrudes in the pressure introduction port along with the introduction direction from one end of the connector case, and has a concavity hollowed in a direction perpendicular to the introduction direction; a sensor chip having a pressure gauge on one surface of the chip in the concavity; a terminal having one end inserted and molded in the connector case; and a bonding wire that electrically connects the sensor chip and the one end of the terminal. The connector case seals a connection portion between the bonding wire and the terminal, a connection portion between the boding wire and the sensor chip, and the bonding wire.

What is claimed is: 1. A pressure sensor comprising:a housing having a pressure introduction port; anda connector case integrated with the housing,wherein the pressure introduction port has a first opening for introducing a pressure medium into the pressure introducing port along with an introduction direction so that the pressure medium reaches the connector case,wherein the connector case includes:a protruding portion that protrudes in the pressure introduction port along with the introduction direction from one end of the connector case, and has a concavity hollowed in a direction perpendicular to the introduction direction;a sensor chip that has a gauge for detecting pressure disposed on one surface of the chip, and is disposed in the concavity so that the one surface of the chip is parallel to the introduction direction;a terminal having one end, which is inserted and molded in the connector case so that the one end is sealed by the connector case; anda bonding wire that electrically connects the sensor chip and the one end of the terminal, andwherein the connector case seals a connection portion between the bonding wire and the terminal, a connection portion between the boding wire and the sensor chip, and the bonding wire.
