Abstract

To provide a photosensitive coloring composition for an infrared light pass filter enabling rectangle properties of a cross section and controllability of a line width in the infrared light pass filter to be enhanced, and to provide an infrared light pass filter, a manufacturing method of a photosensitive composition for an infrared light pass filter, and a manufacturing method of an infrared light pass filter.SOLUTION: A photosensitive coloring composition for an infrared light pass filter includes a coloring agent, a polymerizable compound, a photoinitiator and a polymerization inhibitor. The polymerizable compound includes a first (meth)acrylate having three or more functional groups and containing amino acid. A percentage of a mass of the first (meth)acrylate with regard to a mass of the photoinitiator is 50% to 500%. A percentage of a mass of the polymerization initiator with regard to a mass of the photoinitiator is 3% to 30%.SELECTED DRAWING: None
