A power generation device comprising: a housing; a first power generator held in the housing so as to be allowed to vibrate; and a second power generator held in the housing so as to be allowed to vibrate, the second power generator being electrically isolated from the first power generator, wherein the first power generator comprises: a first substrate including a first fixed end fixed to a location near a middle of the housing and a first free end disposed at a location that is nearer to an end of the housing than to the first fixed end; and a first power generating part formed on the first substrate, the second power generator comprises: a second substrate including a second fixed end fixed to a location near the middle of the housing and a second free end disposed at a location that is nearer to an end of the housing than to the second fixed end; and a second power generating part formed on the second substrate, on condition that a direction the first substrate extends from the first fixed end toward the first free end is designated as a first direction and a direction the second substrate extends from the second fixed end toward the second free end is designated as a second direction, the first direction and the second direction are opposite to each other, and the second fixed end is disposed so as to be shifted relative to the first fixed end in the second direction, characterized in that the first fixed end comprises: a first protrusion including a first protrusion end and projecting in the second direction; and a first electrode formed on the first protrusion, the first electrode being electrically connected to the first power generating part, and the second fixed end comprises: a second protrusion including a second protrusion end and projecting in the first direction, the second protrusion end being located so as to be shifted in the first direction relative to the first protrusion end; and a second electrode formed on the second protrusion, the second electrode being electrically connected to the second power generating part. a housing; a first power generator held in the housing so as to be allowed to vibrate;
