Provided is a sterilization case whereby the size of the case itself can be reduced, and it is possible to reliably sterilize not only the surface of a mobile communication device but hidden portions thereof as well, the amount of space used for sterilization of the mobile communication device can be reduced, and charging and sterilization can be performed simultaneously. A sterilization case 1-1 is provided with a case main body 2 and a cover body 3. The case main body 2 is provided with a voltage supplying part 6 and a loading part 4 having an electrode sheet 5. The voltage supplying part 6 is provided with a boosting circuit 61, a direct-current conversion circuit 62, a switch circuit 63, and a sterilization meter 64. The boosting circuit 61 supplies the voltage necessary to generate ozone to the electrode sheet 5. The direct-current conversion circuit 62 performs conversion to a power source voltage of a smartphone 100 as the mobile communication device and outputs to a male connector 7. The male connector 7 can be connected to a female connector 101 of the smartphone 100. The cover body 3 is attached to the case main body 2 so as to be able to open and close.
