FIG. 2 shows a cross-sectional view of the heat-sensitive element. This heat-sensitive element 3 has a pair of metal electrodes 5 formed on one side of an insulating substrate 4 made of ceramic or the like by printing, baking, vapor deposition, sputtering, etc.
A heat-sensitive resistive film 6 such as a thermistor film or platinum resistive film is placed in between.
is formed, a lead wire 7 is electrically connected and fixed to the electrode 5, and the electrode 5 and the heat-sensitive resistive film 6 are further coated with a protective coating 8 of glass, resin, or the like. Then, as shown in FIG. 8, the lead wire 7 of the heat-sensitive element 3 is inserted into the inner passage 10 of the two-hole ceramic tube 9, which has a concave tip.
After inserting from the side end so that the connection part between the electrode 5 and the lead wire 7 is located in the recessed part 11 as shown in FIG. This is a temperature sensor with a structure in which it is injected, dried or baked, and then fixed with adhesive.

With this configuration, the shape and dimensions of the thermal element 3 are mostly determined by the precision of cutting or shaping the insulating substrate, so it is easy to manufacture a very uniform one, and the variation in thermal response is also very small. Also, since the thermal element 3 is formed by forming a thick or thin temperature-sensitive resistive film on the insulating substrate 4, it is easy to manufacture a very small one with a small heat capacity and excellent thermal response. Furthermore, the thermal element 3 and the ceramic tube 9
The thermal element 3 is fixed at the position of the recessed portion 11.
In addition, it is suitable for mass production because no unnecessary load is applied to the joint of the lead wire 7. The thermal resistance film 6, the electrode 5 surface, the connection part of the lead wire 7, etc. are all protected by resin or glass, etc., so they are completely isolated from the outside air, resulting in a highly reliable product.
