Kind Code:
A1
Abstract:
Provided are: a joining structure making it possible to join resin plates together without needing to provide a surplus resin plate section for joining, and offering excellent workability in the joining together of resin plates; a method of producing same; and a wire exterior cover using the joining structure. A joining structure 1 comprises a joining part 10 formed by butt-welding a plate surface part 22 of a first resin plate 21 made of a first resin, and an end surface part 24 of a second resin plate 23 made of a second resin. In the joining structure, a foam resin is used for the first resin and a foam resin or a non-foam resin is used for the second resin. The joining part 10 has a welding recess 25 in a surface 22a of the plate surface part 22. In an internal corner 10a of a reverse surface 22b, there is a padding section 27 formed by melt-flowing and solidifying of at least the first resin out of the first resin and the second resin.
