Abstract: A temperature sensor having a heat sensing portion including silicone rubber having thermal expansion and contraction characteristics which are linear with respect to changes in temperature, and an responsively operating portion adapted to operate by thermal expansion and contraction of the silicone rubber. The silicone rubber expands as the ambient temperature around the heat sensing portion rises, and the silicone rubber contracts as the ambient temperature decreases. The operating portion operate in response this expansion or contraction, thereby detecting the temperature change.
