Abstract: PURPOSE: To enhance resistance for thermal shock, prevent peeling-off in a jointed face and improve reliability by forming a porous titanium oxide layer on a titanium foil and providing an upper electrode of gas transmission composed of noble metal thereon. CONSTITUTION: A titanium foil(Ti) 2 is bonded to an aluminum substrate 1 by an epoxy bonding agent, a porous oxidation layer 3 of titanium oxide (TiO2 ) is formed by anode oxidation on the half of the upper face, and heating vapor treatment is performed to be stabilized. An upper electrode 4 of gas transmission composed of noble metal is formed on the oxidation layer 3 by deposition or sputtering, and the area is reduced by being irradiated with laser at need. Impedance is regulated, and outside taken-out conductors 5, 5 are connected to the upper face of the Ti foil 2 and the electrode 4 on which the oxidation layer 3 is not formed.  When such constitution is performed, resistance for abrupt temperature change is enhanced because a thermal expansion coefficient difference is very small, peeling-off in a jointed face and cracks of the oxidation layer 3 are difficult to produce, and reliability is improved.
