There is provided a packaging bag capable of easily taking out an inner content of a desired amount from a packaging bag. The packaging bag provided with a fastener forms a packaging bag 1 by connecting a bag body 2 to a spout unit 3 as an independent member. The spout unit 3 is composed of opposing wall surface portions 11 and a fastener provided on inner surfaces of these wall surface portions 11, which are integrally formed through an injection molding process. The spout unit 3 includes a connection opening 15 for connecting one side end to the bag body 2 with the fastener 13 being boundary thereof and a closed portion 16 forming the other side end as the end edge of the packaging bag. A seal-opening portion 20 to be torn so as to separate the spout unit is formed to a portion between the closed portion 16 and the fastener 13.
