Abstract

PURPOSE: To obtain a head shell featuring a large inner loss, high heat resistance and low cost by using the composite material of the organic material such as the vinyl chloride, etc. and the solid powder and giving at least the surface oxidation to the organic material after molding.
CONSTITUTION: The composite material is produced with the organic material such as the vinyl chloride or the like and the solid powder like the graphite powder, etc. which is not fused under 500°C or less. Using this composite material, the head shell is molded into a desired shape. And the molded product is heated up to 250W 300°C in the air (oxidizing atmosphere) to give at least the surface oxidation to the molded product. Thus a head shell featuring a high relative elastic modulus can be obtained.
