Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical filter that ensures compatibility between excellent visible-light transmittance and near-infrared cut performance, even when an incident angle increases, with reduced height of a device and the like including a solid imaging device or an environmental light sensor, and also has excellent heat resistant properties (solder reflow resistance) and improved crack resistance.SOLUTION: An optical filter has a transparent resin-made base material containing a compound (A) having an absorption maximum at wavelengths of 600-800 nm, and a dielectric multilayer formed on at least one side of the base material, and satisfies specific requirements.SELECTED DRAWING: Figure 1
