Abstract: The objective is to provide a finger shape estimating device that can estimate the image most similar to a finger image quickly and with high precision, and that can facilitate construction of a database. Provided is a finger shape estimating device provided with a matching part that reads second shape data in a specific data set from a database that has multiple data sets in which finger angle data, second shape data relating to dimensions in the vertical direction and the horizontal direction of a second finger image of said finger, and second image feature quantities in the second finger image form a set, to match the second shape data and first shape data related to dimensions in the vertical direction and the horizontal direction in a separately acquired first finger image, and an estimating part that matches the second image feature quantities in the data set comprising the compatible second shape data, from matching by the matching part, with first image feature quantities in the first finger image, and estimates the finger shape in the first finger image.
