A paper box for packing detergent which is provided at its inner surface with a strip-shaped inlet so that the inlet closes a tear tape portion to be cut off when the box is opened and which is designed to reduce manufacturing cost, improve productivity and maintain watertightness. The paper box has four vertical wall members, top members extended from upper ends of the vertical wall members, bottom members extended from lower ends of the vertical wall members, a tear tape portion integrally formed at upper portions of three vertical wall members selected from the four vertical wall members, and a strip-shaped inlet attached to inner surfaces of the three vertical wall members such that the tear tape portion is covered with the inlet so as to ensure watertightness against the tear tape portion.
