To realize a multi-dimensional power generating device capable of efficiently converting multi-dimensional kinetic energy into electric energy.

A polyhedron space whose peak point is inscribed to a virtual sphere is virtualized in a virtual spherical space, and a pipe with a sealed structure is arranged on each ridge line of the virtualized polyhedron space. A power generation section 1 provided with a hollow power generation coil 1b and a permanent magnet 1c housed movably in the power generation coil is provided in a pipe 1a on plural ridge lines in different directions. A rectification section 2 provided with a rectifier 2b, and a power storage section 3 provided with a storage cell 3b are provided in a pipe on the other ridge line.Above constitution and following constitution are configured to convert multi-dimensional kinetic energy into electric energy. The permanent magnet of the power generation section 1 is relatively moved in the power generation coil by an external force applied to the pipe, so as to induce a voltage in the power generation coil, and the induced voltage is rectified by the rectification section 2, so as to charge the power storage section (storage cell) 3.
