PROBLEM TO BE SOLVED: To provide a secondary battery module which enables a secondary battery to be charged non-contact and which is compactly built in whole to meet the need for downsized load equipment and further excels in dust- and water-proof performance, for improved reliability in a long period of use.SOLUTION: The secondary battery module comprises a secondary battery 1, a charge control circuit, a control circuit board 2, a case body 6 housing the foregoing, and an input/output terminal 7. A resonance circuit 11 of the charge control circuit includes a power receiving coil 5 and a resonance capacitor 15. The secondary battery 1, as well as a battery terminal 8 connected to the secondary battery 1, a buffer 4 to absorb an expansion deformation of the secondary battery 1 at charge time, a magnetic shield body 4, and the power receiving coil 5 are accommodated at multiple stages inside the case body 6. The case body 6 is composed of a case main body 30 provided with an assembly opening 31 and a lid 32 closing up the assembly opening 31. A terminal window 42 is opened in a flat surface of the lid 32, and the input/output terminal 7 is exposed through the terminal window to the outside of the case body 6. |
