A pouch of the present invention comprises a front and a rear walls and a narrow pouring portion, and at least one wall portion is partially protruded to an outward direction of the pouch to be provided with a bulge portion having a hollow structure at vicinity of the pouring portion. Alternatively, a cut line of the pouring portion is positioned based on a vertex of a vertical angle of an assumed right triangle which is drawn at the pouring portion by the predetermined regulations. A half-cut line as an opening aid may be provided to a position to be opened of the pouch, the half-cut line being formed so as to have a combination of a deep part and a shallow part and/or a combination of a wide part and a narrow part. The bulge portion may be formed by subjecting a preheated resin film to press molding with the use of a die comprising a cavity and a core, and then cooling the thus press-molded resin film while it is held in the die.
