Insulation sheet and disk device provided with the same

摘要

A disk device has a motor provided on a bottom wall of a case. A PCB is located opposite an outer surface of the bottom wall of the case, and an insulation sheet is sandwiched between the outer surface of the bottom wall and the PCB. The insulation sheet has a sheet body formed of an insulator and located opposite the outer surface of the bottom wall and a plurality of damping members provided independently of one another on the sheet body. The damping members include a first damping member situated near the motor and abutting against the PCB and a second damping member abutting against an electronic component mounted on the PCB.
