<p>[PROBLEMS] To provide a joint structure composed of two or more structures which has an excellent joint at the joint area between the structures and which serves as a microstructure or micro-component. [MEANS FOR SOLVING PROBLEMS] A joint structure manufactured by jointing a first structure with a second structure at the smooth surfaces of the structures opposed from each other to form a micro-structure or the like, at least one of the first and second structures being made of a resin composition comprising a polypropylene resin and a hydrogenated derivative of a block copolymer represented by the general formula: X-Y, an alkoxy or alkoxysilane compound or a mixture of an alkoxy or alkoxysilane compound with a hydrogenated derivative of a block copolymer represented by the general formula: X-Y being applied onto the joint area between the first and second structures and adhered to each other with heating (in the formula: X-Y, X represents a polymer block incompatible with the polypropylene resin and Y represents an elastomeric polymer block of a conjugated diene.</p> |
