A multiple-glazed glass unit of the present invention is adapted to separate an indoor space and an outdoor space and includes a pair of glass panes opposed across a gap layer to be spaced at a predetermined distance from each other. Low-emissivity (Low-E) films are formed on both principal surfaces of one of the pair of glass panes that is located closer to the indoor space. The low-emissivity film formed on one of the two principal surfaces that faces the indoor space has an arithmetic average surface roughness Ra of 14 nm or less. This multiple-glazed glass unit is configurable to have a higher SHGC value ever than before as well as keeping a low U-value.
