PROBLEM TO BE SOLVED: To prevent the existence of a secondary coil for non-contact charge from preventing discharge of gas generated during secondary battery charging to the outside by forming a gas discharge path to the outside of a device body in an opening portion penetrating a coil bobbin of the secondary coil of a charge type electric device. SOLUTION: In a charging electric device incorporating a secondary coil 3 for electromagnetic, dielectric coupling with a primary coil on a charger side and a secondary battery 2, a gas discharge path (composed of a pipe 21 and a through hole 13) connecting the secondary battery 2 and the device body 1 outside is formed in an opening portion penetration a coil bobbin 30 of the secondary coil 3. When the coil bobbin is a waterproof sealing material integrally molded on an opening portion side thereof, the coil bobbin itself can be a member for gas discharge path, and further when the coil bobbin 30 is a mold of the waterproof sealing material, the coil bobbin 30 can be a member for the gas discharge path without employing additional waterproof sealing material. |
