PROBLEM TO BE SOLVED: To provide a hand which is small in deflection, in distortion, and is light-weight. SOLUTION: The hand for a transfer apparatus is a laminate which is made up of a layer of composite material of carbon fibers and a resin and a layer of metal. The hand has a bending modulus of elasticity of 130 GPa or more in its longitudinal direction, and the metal is an aluminum alloy. The carbon fiber has a tensile modulus of 50 t/mm<2> or more, thermal conductivity of 100 W/mK or more, and thermal expansion coefficient of 0/ deg.C or less. The carbon fibers are used as prepregs drawn and arranged in one direction. The prepregs are laminated so that the surfaces of the prepregs are parallel to a surface of the transfer hand which carries a transfer object thereon. The laminate is of a three-layer structure of a layer of composite material consisting of the carbon fibers and a resin, a metal layer, a layer of composite material of the carbon fibers and a resin, laminated sequentially from the hand transfer- object carrying surface. |
