PURPOSE:To improve sensitivity and responsiveness by laminating and providing a temp. detecting element, electrode for heating and lithium chloride layer on one main surface of an electrically insulating base plate and providing an electrode for heating and lithium chloride layer on the other surface. CONSTITUTION:Platinum paste is printed on one main surface of an electrical insulating base plate 1 consisting of aluminum and is calcined to form a temp. detecting element 2. A protective insulating layer 3 consisting of a glass layer is coated thereon and electrodes 4 for heating consisting of a pair of comb-shaped gold electrodes are formed on the layer 3 and the rear of the plate 1. Lithium chloride layers 5 are coated thereon. The temp. of the lithium chloride layer balanced with the atmosphere temp. is accurately detected with good sensitivity and responsiveness and since the layer 5 and the electrode 4 for heating are provided further on the other surface of the plate 1 on which the element 2 is not provided, the responsiveness is further improved. |
