<p><P>PROBLEM TO BE SOLVED: To reduce the heat generation of a housing of an electronic apparatus without changing a material forming the housing of the electronic apparatus. <P>SOLUTION: A charging device 100 which transmits charging power to an electronic timepiece 200 having a secondary-side core 220 wound with a secondary-side coil 210 comprises a primary-side core 120 disposed opposite coaxially with the secondary-side core 220, a primary-side coil 110 wound around a primary-side core 120 and generating induced electromotive force at the secondary-side coil 210 by generating magnetic flux together with the primary-side core 120 to transmits the charging power to the electronic timepiece 200, and a heat insulating material 130 having a covering surface covering the surface of the primary-side coil 110 opposed to the electronic timepieces 200 between the primary-side coil 110 and electronic timepiece 200 to suppress heat conduction of heat generated by the primary-side coil 110 to the electronic timepiece 200. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
