Provided are a joining structure, a joining method, an exterior body for a wire harness, and a wire harness capable of firmly joining members having different physical properties while reducing the thickness of a joint part. The joining structure 10 joins a first member 1 made of a first resin and a second member 2 made of a second resin, wherein: the second resin has physical properties having a higher foaming ratio than the first resin; and a recessed joint part 3 is provided which reaches at least the inside of the first member 1 from the outer surface side of the second member in a state in which the first member 1 and the second member 2 are superimposed. Furthermore, a method for manufacturing the joining structure 10 comprises the steps of: superimposing a first member 1 made of a first resin and a second member 2 made of a second resin having physical properties having a higher foaming ratio than the first resin; and joining the first member 1 and the second member 2 by forming the recessed joint part 3 by pressing and hot-melting the second member 2 until the recessed joint part 3 reaches at least the inside of the first member 1 from the outer surface side of the second member 2.

Embodiments disclosed are directed to a woven fabric band that is capable of being secured to another object using threads or the band itself. The woven fabric band may include an inner layer having a first temperature melting point and an outer layer having a second temperature melting point that is higher than the first temperature melting point. When heat having the first temperature is applied to the woven fabric band, the inner layer of the woven fabric band melts while the outer layer remains in its original state. When the inner layer melts, the inner layer conforms to a first shape. As a result of the inner layer conforming to the first shape, the outer layer also conforms to the same shape.

A multilayer film comprises an adhesive layer A comprising an HMPSA composition (a); a complexable thin layer B comprising a PolyEthylene (PE) composition (b); and a heat-sealable and breakable layer C comprising a PolyEthylene (PE) composition (c). Layers B and C are bonded together by layer A. The film is characterized in that (i) the melt flow indices of compositions (b) and (c), denoted MFI(b) and MFI(c), respectively, are each between 2.5 and 15 g/10 minutes; and (ii) the melt flow index of composition (a), denoted MFI(a), is such that the ratios MFI(a)/MFI(b) and MFI(a)/MFI(c) are each between 1.5 and 10.
