To provide an equipment case capable of enhancing reception sensitivity of an antenna.
This equipment case is provided with attaching recesses 13, 15 to correspond to the antenna 8, on respective inner faces of a metal case main body 3 storing the antenna 8 in its inside, and a metal caseback 5 attached onto a reverse face of the case main body 3, and magnetic members 14 are provided respectively in the attaching recesses 13, 15. An eddy current is restrained from being generated in accompaniment to a magnetic flux of a magnetic field generated in the antenna 8 in each of the case main body 3 and the caseback 5 by the each magnetic member 14, respective wall thicknesses of the case main body 3 and the caseback 5 are also reduced by the attaching recesses 13, 15, a radio wave is made to advance easily from each thinned portion into the case main body 3, an electric resistance is also made large in each of the case main body 3 and the caseback 5, the eddy current is also restrained from being generated in accompaniment to the magnetic flux of the magnetic field generated in the antenna 8 in each of the case main body 3 and the caseback 5, by an increase of the electric resistance, and the reception sensitivity of the antenna 8 is thereby enhanced with those.
