In evaluation of fine ceramic components reliability, it is very important to know residual stress introduced to the material surface in the fabrication process. X-ray diffraction method has been sometimes used to measure the residual stress for ceramics, but there are some difficulties in both high cost and exposure of harmful radiation. In order to overcome such difficulties, a simple indentation method to measure the residual stress was proposed by a committee in JSMS. In order to verify this method, the residual stress induced by a vice was actually measured. The residual stress thus obtained was in good agreement with the stress artificially provided by a vice.
