Abstract: A sintered object of silicon monoxide being used as a material for forming a silicon oxide based thin film in which evaporation residue is 4% or less of the sample mass before measurement when thermogravimetry of a sample of sintered object is performed in a vacuum atmosphere where the heating temperature is 1300 ringC and the pressure is up to 10 Pa. The sintered object can be produced by sintering SiO particles having a grain size of 250 mum or above under a non-oxygen atmosphere after it is press-formed or while being pressed. Since the sintered object exhibits a high evaporation rate, productivity of silicon oxide based thin film can be enhanced when it is used as a material for forming a film. It can be applied widely for forming a silicon oxide based thin film being employed as an electric insulating film, a mechanical protection film, an optical protection film, a gas barrier for packaging a food, and the like.
