The invention provides a shield case of a disk device for shielding electromagnetic noises irradiated from a circuit board of a disk device, which can be downsized. A shield case 15 is divided into two parts, a first shield case 15 A and a second shield case 15 B. While enclosing the whole body of the circuit board 6 therein, the shield case 15 is fixed horizontally to the upper surface of the frame 7. The electromagnetic noises irradiated from the circuit board 6 are shielded by the shield case 15. By covering the circuit board 6 with the shield case 15 for shielding electromagnetic noises, the shield case 15 can be downsized as a compact component, and thus a disk device 1 to which the shield case 15 is assembled can also be downsized.
