Abstract

PURPOSE:To obtain a tone arm of a light weight and high rigidity, by coiling the prepreg of carbon fiber and the graphite flake particle on an aluminum foil with use of resin and in such way that the plate faces overlap with each other. CONSTITUTION:The graphite particle is bound on an aluminum foil or aluminum alloy foil 2 having about 40mum thickness in such way that the plate faces overlap with each other to form a graphite/aluminum lamination sheet 4 containing a layer having about 50-100mum thickness. A carbon fiber resin complex prepreg 1 is put on the sheet 4 to be coiled around a core material 5 as a roll-up member. The core is removed after hardening the resin with application of pressure and heat. In such way, a pipe type tone arm is obtained.
