PURPOSE: An indicator is provided to form a surface processing film having a low reflection, a low resistance and a wave selection and absorption effect. CONSTITUTION: An indicator includes a deposition film consisted of at least three layers including a protection film(9), a conductive film(10) and an absorption film(12) on the surface of an indication plane face. Herein, the deposition film is the protection film of which a first layer(9) is mainly consisted of SiO2 in order from the outer surface of the deposition film, and a second layer(10) is the conductive film consisted of at least one metal selected from a group including Ag, Pd, Pt, Cu, Cr and Au. In addition, a third layer(12) is made up to be the absorption film including a coloring material. Furthermore, the deposition film has the luminous transmittance less than 85%, the luminous reflection less than 2% and the resistance less than 1000 ohms/square.
