PROBLEM TO BE SOLVED: To provide a new azeotrope-like composition exhibiting an azeotropic property or behavior (an azeotrope-like property) close to the azeotrope and capable of replacing a cleaning agent suitably used for degreasing of grease, processed oil, etc., used for metal components as processing or rust prevention and removal of flux in production of a semiconductor and other applications such as a foaming agent, a working medium, a dispersing agent, an electrical insulating agent by using, as a base, a hydrofluoro ether free from fear disrupting an ozone layer and not containing chlorine. SOLUTION: The azeotrope-like composition is composed of a nonafluorobutylmethyl ether and tetrafluoropropanol. The azeotrope-like composition is preferably composed of 80-99.5 wt.% nonafluorobutyl methyl ether and 20-0.5 wt.% 2,2,3,3-tetrafluoropropanol. COPYRIGHT: (C)2006,JPO&NCIPI
