PROBLEM TO BE SOLVED: To provide a power generation device capable of improving productivity.SOLUTION: A power generation device 1 comprises: power generation plates 20a-20d having a diaphragm 22 and a piezoelectric element 21 fixed to one side face of the diaphragm 22, and aligned in an overlapping manner at an interval from each other; and support parts 30a-30h provided between the power generation plates 20a-20d and supporting the power generation plates 20a-20d. The support part 30c contacting one of side faces of the power generation plate 20a is formed of a conductive material, and a first electrode 31a is integrated with the support part 30c. The support part 30a contacting the other side face of the power generation plate 20a is formed of a conductive material, and a second electrode 32a with polarity different from that of the first electrode 31a is formed separately from the support part 30a. The support part 30c is arranged almost at a center position on the side face of the power generation plate 20a, and the support part 30a is arranged almost at a peripheral edge position on the side face of the power generation plate 20a. |
