Summary:PURPOSE:To measure the temperature distribution of the visual field level of an optical microscope directly by forming two metallic wires which forms a thermocouple on a substrate in thin film lines by vapor deposition and providing their hot junction on the substrate. CONSTITUTION:One thin film line 2 of a specific kind of metal and plural thin film lines 3 of a different kind of metal are formed on the substrate 1 of slide glass radially about their hot junction part 5 and those thin film lines 2 and 3 are bonded and connected 9 to wiring following a data selector 6, an amplifier 7 for the thermocouple, and a temperature display device 8 at an end part of the substrate 1 of slide glass. The thin film lines 3 are connected to the thin film line 2 nearby the hot junction part 5 at specific intervals and their connection parts function as hot junction. In this case, the thin film line 2 and thin film lines 3 are about 1mum wide and their connection intervals are about 10mum.
