PROBLEM TO BE SOLVED: To provide a manufacturing method for a lenticular lens sheet by which a black stripe with high contrast, free from a line defect or a printing spot and having small and uniform width is formed with good productivity. SOLUTION: In the manufacturing method for the lenticular lens sheet having many lenticular lenses at least on its incident surface and the black stripe on its emitting surface, light absorbing material is supplied to the recessed part of a recessed and projecting pattern formed on the emitting surface so that the recessed part may be positioned at a light non-transmission part, and a plate-like body is made to abut on the emitting surface and pressed thereto, so that the black stripe is formed in the recessed part.
