PROBLEM TO BE SOLVED: To obtain a glass plate capable of satisfying transparency, mirroring performance and heat insulating effect at the same time by well balancing them, gentle to human and the environment, excellent in comfortability, expressing green color-based glass surface reflection tone and having radio wave permeability. SOLUTION: This glass plate having >=10% excitation purity in the range of visible light wavelength of a reflected light from the glass surface side, expressing green color-based glass surface reflection tone with high color saturation and enhanced in comfortability, has a laminated layer film consisting of a Sn oxide thin film having 10-200nm thickness as a primary layer from the glass surface on the one side surface of a transparent glass plate, at least one thin film selected from a group consisting of a metal such as Ti, SUS or NiCr and a nitride of those metals as main component and having 1-15nm thickness and >=1kΩ/square surface resistivity on the primary layer as a secondary layer and a thin film of Sn oxide having 30-200nm thickness on the secondary layer. Further, one of the first layer or the third layer has 70-200nm thickness.
