PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical modulation element that can be bent at a small curvature. SOLUTION: The manufacturing method of an optical modulation element includes a member forming step to form a front face member, wherein a transparent electrode 111, a non-conductive transparent protective film 121, and a transparent orientation film 131 are laminated on a transparent synthetic resin film 101, and to form a rear-face member wherein an electrode 112 is laminated on a synthetic resin film 102; a projected structure forming step for forming a projected structure 14 in the inside of and along the upper side of an electrode face of the synthetic resin film 101; a cell-generating step for generating a bag-like cell 10 by making the synthetic resin film 102 and the electrode made to face each other, and bonding them after applying an adhesive 15 along both the sides and the lower side of the electrode of the synthetic resin film 101; a liquid crystal injection step for injecting liquid crystal into the cell 10; a pressing and extending step for depressing the cell 10, to press and extend the liquid crystal in the cell to a uniform thickness; and a sealing step for sealing the cell 10 by applying a sealant 17 outside the projected structure 14 of the cell 10.
