Abstract
A power generation device for a mobile body includes power generating units and a holding member. Each power generating unit includes an elastically deformable base member and a piezoelectric film, which are laminated alternately. The holding member holds the power generating units. Each power generating unit has an elongated flat-plate shape. Opposite ends of the power generating unit in a longitudinal direction are held by the holding member such that the power generating unit is in an orientation in which a longitudinal axis is substantially perpendicular to the flow direction of the external fluid. A fixing member is provided at each of the opposite ends in the longitudinal direction of each power generating unit. The power generating units are arranged in the holding member via the fixing members to pivot in accordance with the flow of the external fluid.
