1. A pouch formed into a bag by thermally bonding a film to form an outer peripheral sealing part, the pouch including an accommodating part, in which liquid contents are stored, on an inside of the outer peripheral sealing part, wherein
a fragrance component emission part is formed in the film on at least one side thereof at a position corresponding to the accommodating part,
the fragrance component emission part is composed of at least one of a material removal part or a score, which has a notch form, in a range of part of the film in a thickness direction, and
tensile strength of the film in a fragrance component emission area including the fragrance component emission part in a width direction of the pouch is at least 90 N/50 mm, and tensile strength thereof in a height direction of the pouch is at least 125 N/50 mm,
wherein the material removal parts or scores are formed so as to penetrate a plurality of layers forming the film in the thickness direction except an innermost layer among the plurality of layers forming the film,
wherein the accommodating part, in which the liquid contents are stored, is surrounded by the film on a front and back,
wherein the plurality of the layers forming the film include a fragrance component barrier layer that suppresses transmission of the fragrance components therethrough,
wherein the fragrance component barrier layer has either an inorganic deposited film provided with an inorganic deposited layer, or a coating layer containing a barrier resin coating agent,
wherein a circumferential edge protruding part is formed at a circumferential edge of the material removal parts or scores in a groove shape formed at an inner surface of the film, and
wherein the circumferential edge protruding part rising outwardly from an outer surface of the film is integrally continuous with an outermost layer.
