To provide a method constituted so as to overcome the restriction imposed by a conventional system performing over-molding and capable of efficiently manufacturing a plate, which is made of a transparent plastic material, equipped with an opaque component and has the best aesthetic characteristics, optical characteristics and mechanical characteristics, so as not to cause strain.

An article (1), concretely a transparent plate, which is made of the plastic material and equipped with a component (2) made of the plastic material over-molded at least on a part of the plate (1) by injection/compression excepting the compressed regions (3 and 4) of the connection part between the over-molded component (2) and the plate (1), is manufactured.
