Sensor component

A sensor component to be press-fitted into a mounting hole provided in a housing to detect a physical quantity of a measurement target, the sensor component comprising:

• a sensor body in a rod shape to be press-fitted into the mounting hole;
• a detection means provided on a side of the sensor body in a press-fitting direction of the mounting hole, the detection means being configured to detect the physical quantity of the measurement target;
• and
• a pair of O-rings arranged on the sensor body and capable of coming into close contact with an inner surface of the mounting hole,
• wherein the sensor body is made by two-component molding,
• wherein the sensor body includes:
• a primary mold portion which is made by a primary molding and in which the detection means is embedded;
• a secondary mold portion which is made by a secondary molding and which is provided on an opposite side of the primary mold portion in the press-fitting direction of the mounting hole;
• and
• a border portion between the primary mold portion and the secondary mold portion,
• wherein the primary mold portion includes a first arrangement portion on which one of the pair of O-rings is arranged,
• the secondary mold portion includes a second arrangement portion on which the other of the pair of O-rings is arranged, and
• the second arrangement portion, the border portion, and the first arrangement portion are arranged in this recited order in the press-fitting direction of the mounting hole.
