Near infrared ray absorbent composition, near infrared ray cut filter, manufacturing method of near infrared ray cut filter, solid image pickup element, camera module

Abstract

Provided are a near infrared ray absorbent composition which can form a cured film having excellent heat resistance while maintaining high near infrared ray shielding properties, and a near infrared ray cut filter, a manufacturing method of a near infrared ray cut filter, a solid image pickup element, and a camera module using the near infrared ray absorbent composition. The near infrared ray absorbent composition contains a compound having a partial structure represented by M-X, and a near infrared ray absorbent compound, and a content of the compound having a partial structure represented by M-X is greater than or equal to 15 mass % with respect to a total solid content of the near infrared ray absorbent composition. Here, M is an atom selected from Si, Ti, Zr, and Al, X is one type selected from a hydroxy group, an alkoxy group, an acyloxy group, a phosphoryloxy group, a sulfonyloxy group, an amino group, an oxime group, and O═C(Ra)(Rb), Ra and Rb each independently represent a monovalent organic group, and in a case in which X is O═C(Ra)(Rb), X is bonded to M by an unshared electron pair of an oxygen atom of a carbonyl group.
