METHOD OF MANUFACTURING COMPOSITE FILTER

PROBLEM TO BE SOLVED: To provide a method of manufacturing a composite filter that reduces the increase of haze by preventing the mixing of air bubbles into an adhesive layer without increasing a burden of equipment. SOLUTION: The method of manufacturing a composite filter has (A) a step of preparing a continuous belt-like electromagnetic wave shield sheet which has at least a conductive mesh layer in one surface of a first transparent resin base sheet; (B) a step of preparing a continuous belt-like optical filter with an adhesive layer in one surface of a second transparent resin base sheet to which an optical function is imparted; (C) a step of heating at least the adhesive layer of the continuous belt-like optical filter; (D) a step of obtaining a continuous belt-like composite sheet by cooling at least the adhesive layer of the continuous belt-like optical filter and bonding the surface of the adhesive layer side of the continuous belt-like optical filter to the surface of the conductive mesh layer side of the continuous belt-like electromagnetic wave shield sheet; and (E) a step of dividing the continuous belt-like composite sheet.
