PURPOSE:To prevent the destruction of an electrode even in case of rapid variance of temperature by forming parts where both terminals of the electrode are short-circuited and eliminating these parts in the last stage of an element producing process when the electrode is formed on an electrooptic crystal having a pyroelectric effect. CONSTITUTION:This method prevents the destruction of electrodes 4A and 4B or the like which is caused by inter-electrode discharge due to a rapid variance of temperature because of a narrow gap between them. For example, when electrodes 4A, 4B, 4A', and 4B' are formed on a crystal substrate 1, short-circuit parts (a), (b), etc. are provided preliminarily on the outside of individual chip cut lines A-A, B-B, etc. After forming electrodes, individual chips 1A, 1B, etc. are cut after a prescribed end face polishing process, and then, each cut chip does not include short-circuit parts. Thus, it is unnecessary to control the variance of temperature of the crystal after formation of electrodes, and the destruction of electrodes is prevented. |
