A method for the production of a tubular article resulting from joining by insertion a tubular body possessed of a layer having of a thermoplastic resin composition containing a styrene type elastomer and a polyolefin type resin and a tubular body having of a thermoplastic resin composition containing a polyolefin, having the ratio of the outside diameter of a thin tube and the inner diameter of a thick tube (outside diameter of thin tube/inside diameter of thick tube=X) in the range of 1<X<1.25, interposing an absorbent having an absorption wavelength of 700-2,500 nm in the connected part of the tubular body and/or the tubular body, and irradiating the tubular bodies with a laser beam. By connecting tubular bodies using specific resin compositions and having specific inside diameter and outside diameter, the connected parts can be made to adhere strongly. |
