Abstract
A transparent laminate is constituted as follows. A low refractive index transparent film is formed on a surface of the transparent substrate. n units (3≦n≦5) of high refractive index transparent films and silver type transparent electrical are laminated successively on a surface of the low refractive index transparent film. Another high refractive index transparent film is formed on a surface of the n units, and another low refractive index transparent film is formed on a surface of the other high refractive index transparent film. Each of the low refractive index transparent films is an optically transparent film having a refractive index n,in a range of from 1.3 to 1.6 and each of the high refractive index transparent films is an optically transparent film having a refractive index n,in a range of from 1.9 to 2.5.
