Excellent temperature sensor protection and high reliability against vibration and shock. However, when it is used in a situation where it is repeatedly subjected to stronger vibrations and shocks, for example, when it is attached to a portion where it is repeatedly subjected to strong vibrations and shocks of 100G or more, even if it is a sheath type temperature measuring element as described above, Problems such as disconnection of lead wires may occur. Therefore, an object of the present invention is to provide a sheath-type temperature measuring element in which troubles such as disconnection of the lead wire of the temperature measuring element are unlikely to occur even under the condition of being subjected to stronger vibration or shock.

る。The present inventor has examined the cause of troubles such as disconnection of lead wires in the conventional sheath-type temperature measuring element, and has revealed the following facts. That is,
Since the temperature measuring element and the insulating material around the lead wire are powder such as magnesia powder, the element and the lead wire move, although slightly, when subjected to a strong shock or vibration. When the impact or vibration continues, the displacement of the temperature measuring element and the lead wire gradually increases, leading to disconnection.

ができる。On the other hand, in the sheath type temperature measuring element according to the present invention, the temperature measuring element 2, its lead wire 5 and the connecting portion 5a between the lead wire 5 and the conductive wire 3 are solid in which the inorganic insulating material is mainly contained. Since they are embedded in the integral insulating block 6, they do not move relative to each other even when subjected to shock or vibration.
Therefore, disconnection of the lead wires 5 and 5 of the temperature measuring element 2 does not occur. If the temperature measuring element 2 is supported by the rod-shaped fixed core 9 embedded in the insulating block 6 or is sandwiched by the conductive wires 3 from both sides, the temperature measuring element 2 is not supported when the insulating block 6 is molded. The temperature measuring element 2 can be embedded in the insulating block 6 in a state most effective in preventing disconnection because it is not moved from a fixed position and is embedded in a predetermined position.
