A method for producing an objective substance such as vanillin and vanillic acid is provided. An objective substance is produced from a carbon source or a precursor of the objective substance by using a microorganism having an objective substance-producing ability, which microorganism has been modified so that the activity of an L-cysteine biosynthesis enzyme is increased. | ||||||
