Abstract

PURPOSE:To improve mass-producibility, thermal resistance and physical strength by using a material, obtained by impregrating a light-transmissive inorganic filler and glass cloth with photosetting resin and curing it, for a bobbin. CONSTITUTION:A bobbin 1 is constituted by applying photosetting resin 4 to a base 3 made of glass cloth having superior light transmittivity and excellent thermal resistance or an inorganic filler such as built-up mica. As the photosetting resin 4, epoxy resin, acrylic resin, spirane resin, etc., are used and set by ultraviolet-ray irradiation, obtaining invariably superior thermal resistance.
