Sensor assembly and physical quantity measuring device

A sensor assembly comprising:

• a sensor module comprising:
• a cylindrical portion, in which a measurement target fluid is introducible;
• and a diaphragm provided at an end of the cylindrical portion, the diaphragm comprising a first surface to be in contact with the measurement target fluid, and a second surface opposite the first surface, a detector being provided on the second surface;
• a joint attached with the sensor module, the joint comprising a pressure introduction port configured to introduce the measurement target fluid to the sensor module;
• a cylindrical base member attached to the joint, the cylindrical base member surrounding the sensor module;
• an electronic circuit attached to the base member and configured to receive a detection signal outputted by the detector;
• and
• a temperature sensor electrically connected with the electronic circuit, wherein
• the temperature sensor comprises a temperature detector configured to detect a temperature, and at least one lead wire electrically connecting the temperature detector and the electronic circuit,
• the base member is provided with a receiver configured to receive the temperature detector and the lead wire, and
• the receiver comprises:
• a groove formed on an outer circumferential side of the base member and configured to receive the lead wire;
• a receiver recess formed on an inner circumferential side of the base member and configured to receive the temperature detector;
• and a communication hole for bringing the groove in communication with the receiver recess.
