A transparency evaluation device includes a skin index calculation unit that calculates at least one of a luminance component in a captured image obtained by photographing a skin, a color component in the captured image, and an amount of generation of negative factors in which the luminance component or the color component in the captured image changes locally, as a first index, obtains at least one of an intensity distribution of the luminance component and an intensity distribution of the color component in the captured image, and calculates at least one of smoothness of a change in the luminance component and smoothness of a change in the color component as a second index based on the intensity distributions, and a transparency evaluation unit that evaluates transparency of the skin based on an overall index in which the first index and the second index are combined.
