Optical filter

An optical filter comprising a transparent resin body comprising a transparent resin and having a single layer or multilayer structure, wherein the transparent resin body contains a near ultraviolet absorbing dye (U) which has an absorption maximum at a wavelength of from 370 to 425 nm and a near infrared absorbing dye (A) which has an absorption maximum at a wavelength of from 600 to 800 nm, the optical filter has a wavelength λ(U50) at which the transmittance is 50% in a wavelength band of from 400 to 440 nm, and the optical filter satisfies the following requirements (1), (2) and (4) to (8):

• (1) there are a wavelength λ(UV15) at which the transmittance is 15% and a wavelength λ(UV70) at which the transmittance is 70% in a wavelength band of from 380 to 450 nm, and λ(UV70)-λ(UV15)30 nm,
• (2) there are a wavelength λ(IR15) at which the transmittance is 15% and a wavelength λ(IR70) at which the transmittance is 70% in a wavelength band of from 600 to 720 nm, and λ(IR15)−λ(IR70)60 nm, and
