Abstract
Half shellhas a bowl-like shape, and is composed of a thermoplastic resin composition. The half shellhas a top partand a side part. The thickness Tt of the top partis less than the thickness Ts of the side part. The difference (Ts−Tt) between both thicknesses is 0.02 mm or greater and 0.30 mm or less. Two half shellsand a core covered by the half shellsare placed into a mold comprising an upper portion and a lower portion both of which having a semi hemispherical cavity. Upon clamping, the thermoplastic resin composition is compressed while being heated, resulting in outflow of the excess thermoplastic resin composition from the cavity. A cover is formed having the nominal thickness of 0.3 mm or greater and 1.0 mm or less with remained thermoplastic resin composition.
