PURPOSE:To facilitate the manufacture of a small quantity each of different types of operation sheet by using a photocurable resin consisting of a linear copolymer composed of alpha, beta unsaturated ethylene monomer and a monomer containing a carboxylic group as constituent units, a photopolymerable unsaturated compound and a photopolymerization initiator and exposing and developing the resin to form a projecting key top part. CONSTITUTION:One hundred pts.wt. of linear copolymer with a weight-average molecular weight of 200,000 to 500,000 consisting of 60 to 90wt.% of alpha, beta unsaturated ethylene monomer and 40 to 10weight% of a monomer containing a carboxylic group as constituent units, 5 to 150 pts.wt. of unsaturated compound expressed by formula I (R1, R2 are hydrogen; n is an integer of 1 to 15; X is a 2C to 20C divalent hydrocarbon group; and Y is a divalent organic group expressed by formula II (R3 is a 1C to 10C divalent hydrocarbon group; and n is an integer of 1 to 100)) and 0.1 to 10 pts.wt. of photopolymerable initiator which is sensitized due to an active light are components of a photocurable resin layer formed on a base sheet. In addition, a key top part is formed by exposing to light and developing the photocurable resin at a pressing position.
