PURPOSE:To provide a lens sheet having uniform thickness of a molded body without impairing the external appearance due to shrinkage of the volume when an ionization radiation-setting resin is cured. CONSTITUTION:This lens sheet 1 consists of a lens resin layer 2 in which a lens part 21 comprising plural numbers of lens units 22 made of an ionizing radiation-setting resin is formed on a base body 3. The height 5 of the lens is different by its position. In the lens unit, the sum of the lens height 5, distance 6 from the lens bottom 20 to the base 3 and the thickness 7 of the base body is almost const. at any part of the lens sheet. Further, the distance 6 from the lens bottom 20 to the base body 3 is >=3mum. |
