Abstract
A laser-welded body includes at least three of resin members, which contain a thermoplastic resin including: a first resin member which is a laser-irradiated subject, has an absorbance aof 0.01 to 0.12; a second resin member which has an absorbance aof 0.1 to 0.9 and includes a butted part where ends of one or more resin members are brought into contact with each other; and a third resin member which has an absorbance aof 0.2 to 3.8, and the absorbances a, aexhibited by the second resin member and the third resin member are attributed to the inclusion of nigrosine as a laser beam absorbent therein, and the resin members are overlapped in the above mentioned to form contacted parts at these interfaces, at least a part of the butted part and/or the contacted parts are laser-welded.
