Abstract: A structure includes: a near infrared transmitting filter that shields light in a visible range and allows transmission of at least a part of light in a near infrared range; and a member that is provided on an optical path of the near infrared transmitting filter on at least one of an incidence side into the near infrared transmitting filter or an emission side from the near infrared transmitting filter, allows transmission of light in a near infrared range, and has a refractive index of 1.7 or higher for the light in the near infrared range.

Abstract: There is provided a resist composition containing a resin. The resin includes a repeating unit (a) having one or more *—OY0 groups substituted for an aromatic ring; and a phenolic hydroxyl group (b) or a partial structure (c) represented by Formula (X). Here, the *—OY0 group is a group that is decomposed due to an action of an acid to generate a phenolic hydroxyl group, and Y0 is a specific protective group. In a case where the repeating unit (a) includes none of the phenolic hydroxyl group (b) and the partial structure (c), the repeating unit (a) is a repeating unit in which the *—OY0 group is decomposed due to an action of an acid to generate two or more phenolic hydroxyl groups.

Abstract: A curable composition contains a resin containing a curable group, a colorant, a polymerization inhibitor, and a polymerization initiator. A manufacturing method of the curable composition includes a colorant dispersing step of mixing together the resin containing a curable group, the colorant, and the polymerization inhibitor and a mixing step of mixing together the colorant dispersion and the polymerization initiator so as to obtain the curable composition. A cured film is obtained by curing the curable composition. A color filter, a solid-state imaging element, and an infrared sensor have the cured film. A manufacturing method of the cured film includes a curable composition layer-forming step, an exposure step, and a development step.
