Abstract: A transparent substrate provided with a multilayer film includes: a transparent substrate having two main surfaces; and a multilayer film obtained by laminating a metal oxide layer and a silicon oxide layer in order on at least one of the main surfaces of the transparent substrate. SiOx in at least one silicon oxide layer in the multilayer film satisfies a relationship 1.55?x<2.00. The multilayer film has a luminous transmittance of 20% to 89% and a resistance value of 104 ?/sq or higher. x in SiOx is a value determined by depth direction composition analysis in X-ray photoelectron spectroscopy (XPS) using argon ion sputtering. When the silicon oxide layer is an outermost layer, the value of x is determined excluding a point where a sputtering time is 0 minute.
