Abstract
A resistance film of platinum is formed on an insulating substrate of alumina. The resistance film is divided by grooves passing therethrough to provide a zigzag resistance circuit pattern, and the film forms a pair of terminal electrodes electrically connected to end portions of the resistance circuit pattern, respectively. In order to stop transmission of heat generated in the resistance circuit pattern to the terminal electrodes, gaps for stopping heat conduction are formed between the resistance circuit pattern and each of the terminal electrodes.
