Provided is a laminate having excellent heat resistance. Also, provided are: an optical filter including the laminate; a solid-state imaging element; an image display device; and an infrared sensor. In addition, a kit is provided by which the laminate having excellent heat resistance can be manufactured. The laminate has: a near-infrared absorbing layer containing a near-infrared absorbing pigment; and a color filter layer which is disposed adjacent to the near-infrared absorbing layer in the thickness direction and contains a chromatic color pigment, wherein, in at least one among the near-infrared absorbing layer and the color filter layer, the content of a compound in which an acidic group selected from among a sulfo group, a phosphate group, and a carboxyl group is bonded to a pigment skeleton is 0.1-99.9 mass% with respect to the total mass of compounds containing the pigment skeleton. |
