The present invention provides a glass sheet with a low-emissivity multilayer film having improved properties required for glass products. A glass sheet (10) with a low-emissivity multilayer film according to the present invention includes a glass sheet (1) and a low-emissivity multilayer film (2) supported by the glass sheet (1). The low-emissivity multilayer film (2) has a ZrO2-containing layer (3) disposed on an outermost side of the low-emissivity multilayer film (2) and a transparent conductive layer (4) disposed between the glass sheet (1) and the ZrO2-containing layer (3). A content of ZrO2 in the ZrO2-containing layer (3) is 8 mol % or more and 100 mol % or less. A content of SiO2 in the ZrO2-containing layer (3) is 0 mol % or more and 92 mol % or less. An arithmetic average roughness Ra of a surface (3a) of the ZrO2-containing layer (3) is 12 nm or less, and is smaller than an arithmetic average roughness Ra of a surface (4a) of the transparent conductive layer (4).
