1. A structure comprising:
a light-receiving element:
first pixels constituted of a laminate including a color filter and a rear-infrared cut filter, provided on a light-receiving surface of the light-receiving element; and
second pixels including a near-infrared transmitting filter, provided on the light-receiving surface of the light-receiving element at a position different from a region where the first pixels are provided,
wherein the near-infrared cut filter includes a near-infrared absorbing colorant, a cyclic olefin resin having a glass transition temperature of 100° C. or higher, and a surfactant, and
the near-infrared absorbing colorant is at least one selected from a colorant compound having a cation and an anion in the same molecule, a colorant compound which is a salt of a cationic chromophore and a counter anion, or a colorant compound which is a salt of an anionic chromophore and a counter cation.
