摘要：
A hydrogel particle producing method includes spraying into an atmosphere a dispersion containing an oil component dispersed in an aqueous component solution which contains a gel source of non-crosslinked hydrogel dissolved therein such that formed droplets are cooled to solidify, a gelation temperature of the gel source of non-crosslinked hydrogel being equal to or higher than 30° deg. C.
