Beschreibung
Zusammenfassung:	Provided is a power supply device which has a structure enabling assembly by inserting a battery block into a tubular housing case, and from which the heat energy of a secondary battery cell can be efficiently externally dissipated using a heat dissipation sheet thermally coupled with the battery. The power supply device comprises a battery assembly (40) having a cuboidal outer shape and including battery cells (1), an L-shaped bar (59) disposed on a corner portion extending along a ridge line, a heat dissipation sheet (2) disposed on a heat dissipation surface (48) of the battery assembly (40), and an aramid fiber sheet (3) disposed between an inner surface of a cuboidal housing case (10) and the heat dissipation sheet (2).
