PROBLEM TO BE SOLVED: To improve the generation efficiency of a piezoelectric power generation unit.SOLUTION: An upper support insulator 10 serving as a piezoelectric power generation unit includes: a piezoelectric element 12 which converts pressure into electric energy to output the electric energy; a fixed plate 13 to which the piezoelectric element 12 is fixed; a pressure plate 14 which is provided so as to face the fixed plate 13 across the piezoelectric element 12 and be spaced away from the piezoelectric element 12; and a pressure dispersion member 15a which is provided between the piezoelectric element 12 and the pressure plate 14 and transmits pressure, which acts on the pressure plate 14, to the piezoelectric element 12. |
