1. A method for purifying succinic acid from a succinic acid-containing liquid containing cation which is obtained by fermentation or an enzymatic method, which comprises bringing the succinic acid-containing liquid into contact with an H-type strongly acidic cation-exchange resin in an amount equivalent to or more than the amount of cation other than hydrogen ion contained in the succinic acid-containing liquid, and precipitating a crystal of succinic acid from the obtained ion-exchange-treated liquid to obtain purified succinic acid.
