Abstract: A power generation system to improve the degree of freedom of installation is described herein. A power generation system comprises: first fluid chambers that contain a fluid; a second fluid chamber that contains the fluid; a communication flow channel that communicates the first fluid chambers and the second fluid chamber with each other; first pistons that are disposed such that the fluid in the first fluid chambers can be pressed; a second piston that is disposed such that the fluid in the second fluid chamber can be pressed; and power generation modules that convert pressing forces of the corresponding first pistons into electricity using piezoelectric elements. The power generation elements of the power generation modules generate power when the second piston is pressed, and the pressing force is transmitted to the first pistons via the fluid, and the piezoelectric elements are indirectly pressed due to the force thus transmitted.
