摘要： Provided is a spouted bag body (1) capable of having the same function as that of a check valve and allowing contents to easily come out by tilting a spout downward without applying excessive pressure to a bag body. A spouted bag body includes: a spout (10) having a body portion (20) formed in a cylindrical shape, and a valve portion (40) disposed inside a cylindrical hole of the body portion; and a bag body attached to the body portion to seal an opening of the cylindrical hole on one side, in which the body portion is provided with a narrowed portion (29) which protrudes from an inner surface of the cylindrical hole over an entire circumference thereof, and the valve portion (40) includes a support portion (41) attached to the body portion, and a movable portion (42) which is formed of a material having elasticity, is connected to the support portion, and covers an opening of the narrowed portion (29) on the other side by coming into contact with an edge portion of the opening of the narrowed portion on this named other side.
