PROBLEM TO BE SOLVED: To provide an optical filter that can be inexpensively manufactured while maintaining an excellent electromagnetic wave shielding effect and a near IR ray shielding effect. SOLUTION: In the optical filter 10 for a display to be disposed on a front face P of a display, the structural layers of the filter include an electromagnetic wave shielding layer 15, an NIR reflecting agent dispersion layer 17 prepared by dispersing a near IR ray reflecting agent in a transparent resin layer, and an NIR absorbing pigment dispersion layer 16 prepared by dispersing a near IR ray absorbing pigment in a tacky adhesive layer. Thereby, the optical filter can be inexpensively manufactured by reducing the use amount of the near IR ray absorbing pigment while maintaining an excellent electromagnetic wave shielding effect and a near IR ray shielding effect.
