。[Claims for Utility Model Registration] A chamber portion formed by at least a heat-sensitive plate and a diaphragm forming a heat-sensitive chamber is attached to the mold body, an inner chamber is formed between the chamber portion and the mold body, and an inner chamber is formed within the inner chamber. In the differential heat sensor, the differential heat sensor is provided with a contact that closes due to the displacement of the diaphragm due to thermal expansion of the air in the heat sensitive chamber, and a vent hole is provided in the mold body to adjust the air pressure between the inner chamber and the outside. One side is adhesive, and the diameter is 100 mm.
A differential heat sensor characterized in that the vent hole is covered with a seal having a plurality of micron or smaller pores.
