Abstract
A multi-layered article having a first portion constituted of laminated three resin layers and a second portion extending from the first portion, the first portion being constituted mainly of consecutively laminated resin layers composed of a first resin layer formed of a first resin, a second resin layer formed mainly of a second resin and a third resin layer formed of the first resin, the second portion being constituted of resin layers extending from the first resin layer and the third resin layer which constitute the first portion, the first resin layer constituting the outer surface layer of the multi-layered article, the third resin layer constituting the inner surface layer of the multi-layered article which inner surface layer is opposed to said outer surface layer, the second resin layer being encapsulated with the first resin layer and the third resin layer, the second resin layer having a thickness which decreases towards the second portion, and being discontinued, in a region of the first portion in the vicinity of the second portion.
