Abstract
The present invention provides a photosensitive composition with which a cured film having excellent patterning properties and excellent electrode anticorrosion properties can be produced. In addition, it also provides a cured film formed of the photosensitive composition, a color filter, a light shielding film, an optical element, a solid-state imaging element, an infrared sensor, and a headlight unit.The photosensitive composition of the present invention contains a zirconium nitride-based particle containing one or more selected from the group consisting of zirconium nitride and zirconium oxynitride a resin, a polymerizable compound, and a photopolymerization initiator, in which the zirconium nitride-based particle contains 0.001% to 0.400% by mass of a Fe atom with respect to a total mass of the zirconium nitride-based particle.
