[Problem] To provide a method for manufacturing a tea extract which exhibits rich taste, flavor and sweetness by decomposing proteins, which are contained in tea leaves and which could not sufficiently be decomposed by a conventional protease treatment extraction, and thereby forming amino acids. [Solution] A method for manufacturing a tea extract, including a step (A) for subjecting tea leaves to first-stage enzymatic treatment, a step (B) for increasing the pH of the obtained product by at least 0.1 after the completion of the step (A), and a step (C) for subjecting the resulting product to second-stage enzymatic treatment after the step (B).
