An oil temperature sensor includes a sensor body that detects the temperature of oil. The sensor body is formed by covering a thermistor mounted on a first lead frame and a second lead frame with a resin mold portion. The sensor body is fixed to the housing in a manner that the resin mold portion is buried and a first terminal portion and a second terminal portion are partially exposed to space.

Oil temperature sensor

An oil temperature sensor includes a housing assembly in which a lead frame on which a thermistor for detecting a temperature of oil is mounted is integrated with a housing such that a tip-side terminal portion is exposed outward. The housing includes a groove formed linearly into which a cable-attached terminal is inserted. The groove is opened on both sides of the groove in the extending direction and is also opened in one direction crossing the extending direction. A joint terminal portion and a sheath of a cable are partially inserted into the groove.

A method of manufacturing a sensor body used in an oil temperature sensor includes mounting a thermistor on a scheduled first resin mold portion and a scheduled second resin mold portion. The manufacturing method includes molding the scheduled first resin mold portion, the scheduled second resin mold portion, and the thermistor to form a resin mold portion. The manufacturing method includes cutting connecting portions, after the resin mold portion is formed, and separating a scheduled first-terminal-portion forming portion and a scheduled second-terminal-portion forming portion.
