比に正確さを欠く場合があること等の問題かある。In other words, since conventional temperature detection elements are composed of a humidity detection element and a temperature detection element as separate elements, combining the two inevitably increases the size, and the temperature detection element cannot detect temperature. It is used to compensate for the effects of temperature changes on humidity sensing confectionery, that is, changes in the characteristics of the humidity sensing element due to temperature changes, but when the humidity sensing element and temperature sensing element are separate, the temperature of the humidity sensing element There are problems such as the aspect ratio sometimes lacking accuracy.

In the case of a temperature detection element, a fluorine-containing resin phenol is applied to the entire surface, including each electrode part and a part of each glue board connected to it, and a fluorine-containing resin with a surface tension of 11 dyne / and near F+ is applied. By forming a resin film, it is possible to obtain the effect that the electrode portion can be sufficiently retained even if an atmosphere that causes dew condensation occurs on the surface of the temperature/humidity detection element.
