Claim:
1. A material for molding comprising: carbon fiber bundles including carbon fibers; at least one impregnation aid in an amount of 3 to 15 parts by mass based on 100 parts by mass of the carbon fibers, the at least one impregnation aid adhered mainly to the carbon fiber bundles and satisfying the following requirements 1 and 2; and a polycarbonate in an amount of 66 to 2,000 parts by mass based on 100 parts by mass of the carbon fiber, wherein the impregnation aid is adhered to the carbon fiber bundles prior to coating with the polycarbonate: Requirement 1: the liquid at 300° C. has a viscosity of 10 Pa·s or less Requirement 2: a reduction ratio in glass transition temperature (ΔTg) of larger than 2 [° C./%], the reduction ratio in glass transition temperature (ΔTg) being defined by the following expression (A) including the glass transition temperature Tg wherein the content of impregnation aid [%] is defined by the following expression (B): wherein the material for molding has a core/sheath structure in which the carbon fiber bundles and the at last one impregnation aid are core components and the polycarbonate is a sheath component.
