The present invention relates to a temperature sensor element. The temperature sensor element comprises: a temperature sensor part including a ceramic element for a temperature sensor, a first electrode located on a first surface of the ceramic element for a temperature sensor, a second electrode located on a second surface of the ceramic element for a temperature sensor located on the opposite side to the first surface, a first lead wire connected with the first electrode, and a second lead wire connected with the second electrode; and a protective part which covers the temperature sensor part, and is spaced from the temperature sensor part. Therefore, the present invention reduces damage to a temperature sensor element by preventing internal stress and cracks in a protective part due to the thermal expansion coefficient difference between a protective part and a ceramic element for a temperature sensor in the environment that change in temperature is great, and improves efficiency of manufacturing a temperature sensor element by preventing resistance properties of a ceramic element for a temperature sensor from being changed as a material of a protective part is penetrated into a crystal structure of the ceramic element for a temperature sensor. |
