Abstract
A cassette for accommodating a tape-shaped material having an electrically conductive layer has a contact piece which is disposed on one end face of a take-up reel for winding up the material and which is electrically connected to an electrically conductive layer of the material. The cassette further has a reel retainer which has a grounding contact and which is secured to a cassette casing accommodating the material, the reel retainer being brought into contact with the contact piece. An electrically conductive grease is interposed in the area of contact between the contact piece and the reel retainer. Accordingly, the surfaces of the respective contact portions of the contact piece and the reel retainer are coated with the grease and thereby prevented from being oxidized. Even if dust is generated due to wear of the contact portions, it is trapped by the grease and thereby prevented from scattering.
