Abstract

PURPOSE: To obtain a mark compensation element which indicates a thermal property resembling a detection element and is inactive for a combustible gas by providing a carrier, which is connected to a platinum resistor thermally, on the platinum resistor and heating it to form cobalt oxide after soaking it into cobalt salt solution.
CONSTITUTION: A paste consisting of γ-aluminum oxide, silicasol, etc., is applied to platinum narrow wire coil 1 and is printed to form carrier 2. Next, carrier 2 is caused to include cobalt salt solution such as cobalt surface and cobalt nitrate and is heated to form cobalt oxide, and this cobalt oxide is covered with ventilative cover 5, thereby obtaining the compensation element for a mark detection unit.
