CELL CASE, AND STRUCTURE FOR ATTACHING CELL CASE

[Problem] To provide a cell case, which maintains cell temperature low by reducing heat reception during the time of non-use (at no power generation), while ensuring heat dissipation performance during use (when generating power), and which is capable of suppressing reduction of cell capacity due to thermal degradation, and to provide a structure for attaching the cell case. [Solution] A cell case (100) has a sealed structure, and houses a battery module (180) having at least one cell (182). The cell case has a supporting mechanism (140) for supporting the battery module (180), and which forms a space (S) between the outer surface of the battery module and the inner surface of the case; a first cover layer (184), which has a radiation emissivity larger than that of the outer surface of the battery module, and which is disposed on the outer surface of the cell module; and a second cover layer (124), which has a radiation emissivity larger than that of the inner surface of the case, and which is disposed on the inner surface of the case. The first cover layer (184) and the second cover layer (124) are opposed to each other at least partly through a space (S).
