PURPOSE:To detect strain in a higher temperature atmosphere by using a material consisting of an excellent basic conductor component with specific high temperature resistance temperature characteristics and a specific dielectric material for a resistance body formed on a ceramic base. CONSTITUTION:A circuit pattern 4 is provided on the ceramic base 2 to form a pattern forming body 6. Then a filmy resistance body part 4a constituted by including the specific base conductor component in the specific dielectric material and a circuit pattern 4 consisting of a conductor part 4b made of a normal conductor material are formed on the calcined or uncalcined base 2. Namely, the resistance body part 4a which constitutes the pattern 4 contains one kind of compound powder selected in a group of Ti, Zr, etc. as basic components in the dielectric material made of specific glass, etc. Further, the resistance body part 4a is connected to external equipment, etc., from the base 2 by a conductor part 4b which does not vary in resistance value owing to the deformation of the base body 2. Thus, strain is detected in a higher temperature atmosphere.
