Abstract

PROBLEM TO BE SOLVED: To prevent the deterioration of an output characteristic due to the drop of battery temperature by utilizing heat generated from an electronic circuit of an electronic apparatus for warming the battery. SOLUTION: In the case that a computer is used, for instance, as an electronic apparatus in a place of low ambient temperature, when a holding member 14 is displaced to a non-holding position by operating an operation knob part 14A formed on the holding member 14, a tapered part 14B separates from a tapered part 12C formed at the upper end part of a battery case 7. A heat- transfer member 12 located at a non-transferring position is displaced to a transferring position by the energizing force of a heat-conductive rubber 13, a heat-transfer surface 7A of a battery case 7 comes into a contact state with a heat-transfer surface 12A of the heat-transfer member 12, and the heat generated from a CPU 10 is transferred to the battery case 7 through a heat-transfer plate 11A of a heat-radiating plate 11, the heat-conductive rubber 13 and the heat-transfer member 12. The heat is transferred to a battery 8 through the battery case 7, so that the temperature of the battery 8 does not drop and the battery 8 can be used in the most suitable condition.
