Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of malfunction due to bonding electrodes.SOLUTION: A first bonding electrode 28 is arranged at a position farther from a weight part 4 than electrode parts 8a and 8b: specifically, at the end of a frame part 3 (at a lower end in Figure 1) that opposes the weight part 4 across the electrode parts 8a and 8b. Similarly, a second bonding electrode 29 is arranged at a position farther from a weight part 5 than electrode parts 9a and 9b: specifically, at the end of the frame part 3 (at the lower end in Figure 1) that opposes the weight part 4 across the electrode parts 9a and 9b. This can suppress the occurrence of malfunction due to the expansion of the bonding electrodes 28 and 29, which are left at the frame part 3, at a high temperature and due to deformation caused by leaving them under a high temperature environment for a long period of time, as compared with a case where bonding electrodes 100 and 101 are provided at a narrow part sandwiched by the two weight parts 4 and 5 as in conventional examples.
