摘要： A method for manufacturing a molded article includes applying a photosensitive composition to at least one of a first plate and a second plate to form a coated film. The first plate is pressed against the second plate with the coated film therebetween. The coated film of the photosensitive composition is exposed. The first plate is separated from the second plate. The exposed coated film is heated. At least one of the first plate and the second plate has a pattern including concave and convex on its surface, and the coated film conforms to the pattern in the step of pressing the first plate against the second plate.
