Abstract

PURPOSE:To increase the heat resistant property and to suppress the expansion and shrinkage due to temperature by impregnating a specified resin whose heat resistant property is excellent in a specified base material. CONSTITUTION:The coil bobbin 1 is formed by winding a Nomex paper which is treated with polyamide polymer in a cylindrical form. The resin 1a whose heat resistant property is excellent is impregnated, thereby the expansion and shrinkage are suppressed. The voice coil 2 is wound around the bobbin 1. As for the heat resistant resin to be impregnated in the base material, at least one of phenol resin, epoxy resin, and imide resin is selected.
