Abstract
A light selective transmission type glassaccording to the present invention includes: a glass substrate; and a light selective transmission layerprovided on at least one main surface of the glass substrate. The glass substratehas an average thermal expansion coefficient αat 50° C. to 100° C. of 2.70 ppm/° C. to 3.20 ppm/° C., an average thermal expansion coefficient αat 200° C. to 300° C. of 3.45 ppm/° C. to 3.95 ppm/° C., a value α/αobtained by dividing the average thermal expansion coefficient αat 200° C. to 300° C. by the average thermal expansion coefficient αat 50° C. to 100° C. of 1.20 to 1.30, and a content of an alkali metal oxide being 0% to 0.1%.
