a patterned sheet (18) constituted of a resin sheet (13) made of a transparent thermoplastic resin and a colored pattern (16) formed in a surface of the resin sheet (13); and a base (11) which is made of an inorganic material and has a roughened surface, the patterned sheet (18) having been directly fusion-bonded to the base (11) so that the colored pattern (16) is in direct contact with the roughened surface of the base (11). Due to the constitution, the patterned sheet (18) having a large area can be tenaciously bonded to the base (11) without using any adhesive. Production step simplification is possible and a considerable reduction in production time can be attained. |
