Here, the detection material may be a mixture of gas and solid.

The support part may be bendable so that the external force applied to the heating part is dispersed according to the volume change of the detection material.

Referring to FIG. 7( a ), an external force in a left direction W20 may be applied to the heating unit by the expansion of the detection material.

Conversely, referring to FIG. 7(b) , an external force may be applied to the heating part in the right direction W10 by the expansion of the detection material.

7(a) or 7(b), when an external force biased to the heating part is applied, the support body part 122 is bent, and the heating body part 111 of the heating part is bent and damaged. can be prevented

In addition, when the situation of FIGS. 7 ( a ) and 7 ( b ) occurs at the same time, and a compressive force is generated in the heating body 111 , since the heating body 111 is made of a silicone material, the The heating body 111 may not be damaged.

By bending the support body part 122 instead of the heating body part 111, it is possible to prevent the heating body part 111 from being damaged.

Most of the non-uniform forces generated as the detection material expands can be absorbed while the support body 122 is bent.

Only a small compressive stress may be generated in the heating body 111 .

For example, when the heating body 111 is made of silicon, it can withstand strong compressive stress.

When the detection material returns to its original state (liquid), the support body 122 may return to its original position.
