<p>PROBLEM TO BE SOLVED: To provide a case body which has good touch and excellent durability.SOLUTION: A case body comprises a substrate including an outer layer and an inner layer and a soft layer. The soft layer is composed of a silica gel material, and the soft layer and the inner layer are joined on the surfaces of the outer layer on opposite sides. The soft layer covers the edge of the inner layer. The outer layer is composed of an iron member or a stainless steel member. In the outer layer, a large number of through holes penetrating the outer layer are formed. The inner layer is formed by injecting a molten color resin onto the outer layer, and the molten color resin is charged into the through holes to form a color pattern on the outside surface of the outer layer. The pattern is visible through the soft layer.</p> |
