Abstract

A sensor element that has high measurement precision by providing a resistance-change length ratio corresponding to a direction-specific extension length is provided. The sensor element includes an element body disposed in a sensor body to measure a temperature and a pressure and having a diaphragm deformed based on the temperature or the pressure. Additionally, the sensor element includes pressure-measuring resistors including a second resistor portion and a fourth resistor portion disposed along a diametric direction with respect to a center of an upper surface of the diaphragm and in an extension section on the upper surface of the diaphragm and a first resistor portion and including a third resistor portion disposed outside the second resistor portion or the fourth resistor portion in a compression section on the upper surface of the diaphragm to eliminate a resistance change caused by a pressure-specific temperature change.
