Claim:
A method of manufacturing a hard disc device with a printed wiring board fixed to, comprising the steps of: attaching an adhesive layer in advance to an insulating resin film to form an adhesive film, wherein the adhesive layer has adhesiveness exhibiting temperature higher than normal ambient temperature; winding the adhesive film up to form a roll of the adhesive film so that an exposed surface of the adhesive layer is in contact with the resin film; unwinding the adhesive film from the roll; bringing the exposed surface of the adhesive layer into contact with a buffer layer having elastic attributes and heating the adhesive layer while pressing against the buffer layer; thereby attaching the resin film to the buffer layer with the adhesive layer to form an insulating sheet; and fastening the printed wiring board to a case of the hard disc device in a state that the insulating sheet is located between the printed wiring board and the case of the hard disc device.
