PROBLEM TO BE SOLVED: To provide resin compositions which have good melt flowability and, excellent heat resistance, heat stability and weld strength when formed into molded articles and accordingly, can be applied to molded products (e.g. electric/ electronic parts, mechanical parts, automobile parts and the like) having complicated shapes which require a high level of heat resistance. SOLUTION: The resin compositions comprise an aromatic polysulfone resin having a structural unit represented by formula (1) and a semiaromatic liquid crystal polyester resin having a structural unit represented by formula (2) with a composition ratio of the aromatic polysulfone resin having a structural unit represented by formula (1) of 60-99 wt.% and a composition ratio of the semiaromatic liquid crystal polyester resin having a structural unit represented by formula (2) of 40-1 wt.%, each based on the total weight of the aromatic polysulfone resin having a structural unit represented by formula (1) and a semiaromatic liquid crystal polyester resin having a structural unit represented by formula (2).
