PURPOSE:To obtain a leather-like grip cover which does not generate bleed of white powder as a result of its long use by laminating a skin layer consisting of a specific amount of leather powder with a specific characteristic and a specific amount of synthetic resin as main components on a base material. CONSTITUTION:A skin layer consisting mainly of 5 to 60 wt% of leather powder having 8 wt% or higher of skin component, 2 wt% or lower of oil/fat, a total of 0.5 wt% of lower of Na<+> ion and Ca<2+> ion which can be extracted in water and a mean grain diameter of D50 of 7mum or less and an average deflection of the mentioned grain diameter of 3mum or less, and 95 to 40 wt% of synthetic resin, is laminated on a base material to obtain a leather-like grip cover. Unwoven cloth impregnated with polyurethane resin 51 consists of a fine porous polyurethane resin layer 52, on which a polyurethane resin layer 54 is laminated through an adhesive 53. The unwoven cloth 51, fine porous polyurethane resin layer 52 and polyurethane resin layer 54 contain a specified amount of leather powder A respectively. |
