Abstract: A structure for strain detection is provided with a ceramic main body which is attached to a detection target, in which strain is to be detected, and a stress concentrated section which is formed in the main body and which is fractured at a predetermined strain or greater. Assuming the dimension of the entire main body in one direction is represented by Lm and the dimension of the stress concentrated section in the one direction is represented by Lc, then it holds that Lc
