An object of the present invention is to provide a curable composition capable of forming a cured film excellent in pattern linearity, a light shielding film formed using the curable composition, a color filter, a solid-state imaging device, and an infrared sensor. Another object of the present invention is to provide a pattern formation method using the curable composition and a color filter manufacturing method. The curable composition of the present invention is a curable composition containing a colorant absorbing visible light, a colorant absorbing infrared light, a polymerizable compound, and a photopolymerization initiator, The minimum value of the optical concentration per 1 μm of the film thickness in the region of the wavelength 380 to 1100 nm of the coating film of the curable composition is 1 or more, and The Δ optical concentration obtained from Equation (1) is 1 or less. Equation (1) Δ optical concentration = |OD1-OD2| In formula (1), OD1 represents the minimum value of optical density per 1 μm of film thickness in a region of 380 nm or more and 780 nm or less of the wavelength of the coating film, and OD2 is 1 μm of film thickness in a region of more than 780 nm and 1100 nm of the wavelength of the coating film. It shows the minimum value of the sugar optical density. |
