The present invention addresses the problem of providing a chlorinated-polyolefin-based resin composition which is excellent in terms of adhesiveness and solution stability and of unsusceptibility tochipping. The chlorinated-polyolefin-based resin composition comprises component (A), which is a polyolefin-based resin A having a melting point (TmA), obtained with a differential scanning calorimeter (DSC), in the range of 90-160 DEG C, and component (B), which is a polyolefin-based resin B having a melting point (TmB), obtained with a differential scanning calorimeter (DSC), in the range of 50-130 DEG C, wherein component (A) and/or component (B) is a chlorinated-polyolefin-based resin or component (A) and component (B) are a copolymer thereof which is a chlorinated polyolefin-based resin (|TmA-TmB|>=5 DEG C). 本发明的课题在于，提供附着性、溶液稳定性优异且耐崩裂性优异的氯化聚烯烃系树脂组合物，氯化聚烯烃系树脂组合物，其含有成分(A)：通过差示扫描型量热计(DSC)而得到的熔点(Tm)为90~160℃的范围的聚烯烃系树脂A和成分(B)：通过差示扫描型量热计(DSC)而得到的熔点(Tm)为50~130℃的范围的聚烯烃系树脂B，成分(A)和成分(B)中的至少任一者或它们的共聚物为经氯化的氯化聚烯烃系树脂(其中，｜Tm
