Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a large-sized lenticular lens sheet of a joint type which has high bending strength of joint parts and is hardly destroyable in handling work, etc. SOLUTION: This lenticular lens sheet is formed by joining a plurality of sheets 61 and 62 formed with lenticular lenses on a light incident surface side and a light exit surface side, respectively, in the valley parts of the lenticular lenses on the incident surface side. The valley parts of the incident surface side lenticular lenses in these joint parts 2 are provided with adhesive layers 7 embedded with adhesives having refractive indexes approximately equal to the refractive index of the material constituting the sheets. The surface shape on the incident surface side of the adhesive layers 7 is preferably a curved surface shape which is concave to the incident surface side.
