Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lens holder with which a measurement point can be positioned while its product shape is maintained when ultraviolet or visible light transmittance of a contact lens or an intraocular lens is measured with a spectrophotometer.SOLUTION: There is provided a lens holder including a first lens holding member having a holding surface for holding a concave shape side of a lens, a second lens holding member having a holding surface for holding a convex shape side of the lens, and a lens holding member storage container for mating and storing the first lens holding member and the second lens holding member in a state sandwiching the lens of which transmittance is to be measured. At least a material of a portion of the lens holding member storage container where the lens is stored transmits the light of a wavelength of the measurement light of the spectrophotometer.
