Abstract

See full text

An insulating sheet 13 is manufactured by attaching a buffer layer 21 and a resin film 23 using an adhesive layer 8 that is not adhesive at a normal ambient temperature. Since there is no need to use a release liner when manufacturing the insulating sheet 13, there is no release of a silicone component. Accordingly, when installing a hard disk printed wiring board, the printed wiring board and electronic circuits inside the hard disk will not be damaged by the released silicone.
