[Problem] To provide a novel sweetener, which is free from a risk of diseases caused by the intake of isomerized sugars and overcomes problems encountered in the course of producing a rare sugar-containing syrup or disadvantages in taste, a method for manufacturing the same, and a use thereof. [Solution] A method for manufacturing a sweetener composition, said method comprising : treating sucrose with an acid and/or an enzyme under specific conditions to thereby efficiently decompose sucrose into glucose and fructose; and then isomerizing the obtained mixture using an alkali and/or an enzyme under specific conditions in such a manner as to allow the resultant isomerized product to contain D-psicose mainly as a rare sugar so that the product comprises, at a specific composition ratio, sucrose, D-glucose, D-fructose and rare sugar(s) at least containing D-psicose, or the product comprises, at a specific composition ratio, D-glucose, D-fructose and rare sugar(s) at least containing D-psicose.
