The present invention pertains to: a paddy-rice seed that includes at least one type of powder selected from among metal oxides (brown iron oxide, zinc oxide, and tin oxide)； a method for manufacturing a coated paddy-rice seed by spraying a resin emulsion onto a mixture of the powder containing the metal oxide and the paddy-rice seed, and drying after forming on the rice-seed surface a coating layer including the metal oxide powder and the resin emulsion； a method for manufacturing a coated paddy-rice seed by mixing the paddy-rice seed and an emulsion paste including a resin that includes the metal oxide powder, and drying after forming on the rice-seed surface a coating layer including the metal oxide powder and the resin emulsion； and a composition for a paddy-rice seed coating containing the metal oxide powder and the resin emulsion. According to the present invention, it is possible to provide a coated paddy-rice seed, a method for manufacturing same, and a composition for a paddy-rice seed coating, in which degradation of the paddy-rice seed due to heat generated during the coating step and later steps is substantially eliminated, coating operation efficiency is improved, and bird damage is unlikely.L'invention concerne des graines de riz paddy comprenant au moins un type de poudre choisi parmi des oxydes métalliques (oxyde de fer brun, oxyde de zinc et oxyde d'étain). Elle concerne un procédé de production de graines de riz paddy enrobées, par pulvérisation d'une émulsion de résine sur un mélange de poudre contenant l'oxyde métallique et les graines de riz paddy, et séchage après formation à la surface des graines de riz d'une couche d'enrobage comprenant la poudre d'oxyde métallique et l'émulsion de résine. Elle concerne un procédé de production de graines de riz paddy enrobées, par mélange des graines de riz paddy et d'une émulsion en pâte qui comprend une résine contenant la poudre d'oxyde métallique, et séchage après formation à la surface des graines de r
