A light selective transmission filter that selectively blocks light, has high transmittance at a specific wavelength such as visible light, and has excellent heat resistance, and a lens unit having the light selective transmission filter. A light selective transmission filter for an optical member that selectively reduces light transmittance, the light selective transmission filter having functional films on both surfaces of a reflow resistant resin film, and the light A lens unit including a selective transmission filter and a lens.
