The translation device is provided with a character string output unit (1141), a fixed phrase obtaining unit (1142), a matching unit (1143), a division processing unit (1145), and a translation resultoutput unit (115). The character string output unit (1141) outputs a plurality of character strings in order of character string length, the plurality of character strings including the first character of a text in a first language, and each of the character strings being at least a part of the text. The fixed phrase obtaining unit (1142) obtains a fixed phrase in the first language correspondingto a target language phrase in a second language. The matching unit (1143) calculates the similarity between each of the plurality of character strings and the fixed phrase in order of character string length. The division processing unit (1145) divides the text at a position corresponding to the highest similarity among similarities exceeding a first threshold value. The translation result output unit (115) outputs the target language phrase as a translated phrase of the divided text.
