PROBLEM TO BE SOLVED: To provide a device and a method for measuring the printing width of a lenticular lens sheet by which the width of the light absorbing layer of the lenticular lens sheet can efficiently be measured. SOLUTION: The device 10 for measuring the printing width of the light absorbing layer 3 of the lenticular lens sheet having a plurality of incident side lenses 21 and a plurality of light absorbing layers 3 juxtaposed at the light non-condensing parts of the lenses 21 on an opposite surface opposite to a surface where the lenses 21 are juxtaposed is equipped with a photographing device 12 photographing the opposite surface so as to acquire the image of a plurality of light absorbing layers 3, and an image evaluation device 14 analyzing the image of the light absorbing layers 3 acquired by the photographing device 12 so as to measure luminance change on the opposite surface and measuring the printing width of a plurality of light absorbing layers 3 based on the luminance change.
