摘要:
A light selective transmission type glass 10 according to the present invention includes: a glass substrate 12; and a light selective transmission layer 11 provided on at least one main surface of the glass substrate 12. The glass substrate 12 has an average thermal expansion coefficient α50/100 at 50° C. to 100° C. of 2.70 ppm/° C. to 3.20 ppm/° C., an average thermal expansion coefficient α200/300 at 200° C. to 300° C. of 3.45 ppm/° C. to 3.95 ppm/° C., a value α200/300/α50/100 obtained by dividing the average thermal expansion coefficient α200/300 at 200° C. to 300° C. by the average thermal expansion coefficient α50/100 at 50° C. to 100° C. of 1.20 to 1.30, and a content of an alkali metal oxide being 0% to 0.1%.
