<p>PURPOSE: A case, a portable terminal, and a manufacturing method thereof are provided to manufacture cases of various colors by forming a plurality of coating layers by an oxide with different refractive indexes. CONSTITUTION: A case for a portable terminal comprises a base(151), a first and a second optical permeability coating layers(153a,153b). The base forms the external shape of the case for the portable terminal. The first and the second optical permeability coating layer are laminated on the base. The first and the second optical permeability coating layer are composed of different materials. The second optical permeability coating layer is composed of a material with a refractive index which is higher than the index of the material of the first optical permeability coating layer. The second optical permeability coating layer is formed between a plurality of a first optical permeability coating layers.</p> |
