Abstract
An exterior part (200) includes (a) a structure color generation portion (210) having a minute shape (structure color generation region (211)) formed therein, light in a visible light range being produced from the minute shape by a physical phenomenon such as interference or diffraction with the incidence of light, and (b) a resin portion (220) that is made of resin having a light transmitting property and serves as the outer surface of a product, (c) the structure color generation portion (210) and the resin portion (220) are formed by molding, and (d) the structure color generation portion (210) is made of resin different from the resin of the resin portion (220), and covered with the resin portion (220).
Claims20
An exterior part configuring an outer part of a product, comprising:
- a resin portion that is made of resin having a light transmitting property and serves as an outer surface of the product;
- and
- a structure color generation portion having formed therein with a minute shape from which light in a visible light range is produced by a physical phenomenon such as interference or diffraction with incidence of light,
- wherein the resin portion and the structure color generation portion are formed by molding.
A molding method of molding an exterior part configuring an outer part of a product, comprising:
- a first molding step of placing a part having a first surface with a minute shape formed thereon, light in a visible light range being produced from the minute shape by a physical phenomenon such as interference or diffraction with incidence of light, in a mold having a second surface for forming an outer surface of the product so that the first surface and the second surface face each other;
- a second molding step of closing the mold so as to have a space between the first surface and the second surface, and filling the space with a molding material having a light transmitting property after hardening;
- and
- a third molding step of removing from the mold a molded product having the minute shape protected by the molding material as the exterior part.
