The palmprint region dividing device for dividing a palmprint into each specific region includes a ridge line pattern extracting unit for extracting a ridge line pattern of the palmprint in question from an image of the input palmprint, a hypothenar and thenar regions detecting unit for detecting a hypothenar region and a thenar region using the ridge line pattern extracted, a crossing point detecting unit for detecting a crossing point from the ridge line pattern of a boundary between the hypothenar region and the thenar region, a division direction determining unit for determining a division direction based on a ridge line direction in the vicinity of the crossing point, and a division position determining unit for determining a division position which is a position at which the palmprint in question is to be divided into each region based on a boundary between the hypothenar region and the thenar region, a division direction, and a difference in a ridge line pattern in the thenar region and a interdigital creases region.
