An object of the present invention is to provide a pouch and a liquid-containing pouch having high resistance to falling breakage. A pouch (10) is a pouch formed into a bag by an outer peripheral sealing part (20). The pouch includes an accommodating part (30). A fragrance component emission part (40) is formed in the film on at least one side at a position corresponding to the accommodating part. The fragrance component emission part is composed of a material removal part (41) or a score having a notch form, in a range of part of the film in the thickness direction thereof. The tensile strength of the film in a fragrance component emission area in the width direction of the pouch is at least 90 N/50 mm, and the tensile strength thereof in the height direction of the pouch is at least 125 N/50 mm.
