Power generation device

A power generation device for converting an external force to electricity by using a power generation element and the power generation device comprises:

• a plurality of the power generation plates juxtaposed in an overlapping state at an interval from each other, the power generation plate having the power generation element or the power generation plate having a substantially plate-shaped conductive member having flexibility and the power generation element fixed at least to either one of side surfaces of the conductive member;
• and
• a plurality of support means provided between the plurality of power generation plates and supporting the plurality of power generation plates, wherein
• the plurality of support means are disposed so that, when an external force is applied to the power generation device, at least a part of the plurality of power generation plates is deformable along a juxtaposed direction of the plurality of power generation plates,
• the support means in contact with one of the side surfaces of at least one power generation plate in at least a part of the plurality of power generation plates is formed of a conductive material, a first electrode for withdrawing an electric current generated in the power generation plate to an outside with respect to the support means is formed integrally with or separately from the support means, the support means in contact with the other of the side surfaces of the power generation plate is formed of the conductive material, and a second electrode for withdrawing the electric current generated in the power generation plate to the outside with respect to the support means and with a polarity different from that of the first electrode, is formed integrally with or separately from the support means,
• the support means electrically connected to the first electrode is disposed at a substantially center position or at a substantially peripheral position on the side surface of the power generation plate and the support means electrically connected to the second electrode is disposed at the substantially peripheral position on the side surface of the power generation plate,
• the support means electrically connected to the first electrode is disposed at the substantially center position on the side surface of the power generation plate,
• the support means electrically connected to the first electrode comprises:
• a first contact portion provided integrally with the first electrode and in contact with one of a pair of the power generation plates supported by the support means;
• and
• a second contact portion provided integrally with the first electrode and in contact with the other of the pair of the power generation plates.
