Abstract The present invention addresses a problem of providing a high quality seamless capsule, with excellent uniformity of shell thickness and virtually no eyes in the shell.The problem can be solved by manufacturing a seamless capsule using a shell composition comprising at least one polysaccharide selected from the group consisting of agar, carrageenan and gellan gum, and a PVA copolymer comprising the following structural units: (i) polyvinyl alcohol, (ii) at least one unsaturated carboxylic acid selected from the group consisting of acrylic acid, methacrylic acid, fumaric acid and maleic acid, and (iii) at least one unsaturated carboxylic acid ester selected from the group consisting of compounds represented by formula [I]:        H2C=C(R1)-COOR2     [I](wherein R1represents a hydrogen atom or a methyl group, and R2represents an alkyl group having 1 to 4 carbon atoms).
