To provide a destruction device for a storage device, by which data in a storage device such as a hard disk drive can not be quickly and easily read with simple constitution.

The device is provided with a liquid push-out device 10 formed in a cylinder gun type for pushing out liquid A in a hard disk drive, and a nozzle inserting device 20 constituted integrally with the liquid push-out device 10. The hard disk drive is held between holding parts 21 so that the tip of a nozzle part 12 attached to the holding part 21 is positioned on a seal part 105 stuck to the respiratory hole of the hard disk drive, and a gripping part is gripped strongly. Thereby, the tip of the nozzle part breaks the seal part or the like, and the tip part is inserted into the hard disk drive 100. Next, a piston rod 13 is pushed to inject the liquid housed in a liquid housing part 11 into the hard disk drive.
