PROBLEM TO BE SOLVED: To easily unseal an opening of a body part of a sealed paper container, which is composed of a laminated material, for example, of paper and a plastic film used to enhance barrier properties, by using only finger strength. SOLUTION: This sealed paper container A, which is made of the laminated material composed mainly of the paper, is composed of the rectangular column-shaped body part 1, a top part 2 and a bottom part 3; the body part 1 is equipped with a front plate 11, a side plate, a rear plate and a side plate; and the top part 2 and the bottom part 3 are equipped with front shape-retaining surfaces which are connected continuously to the front plate 11, rear shape-retaining surfaces which are connected continuously to the rear plate, shape-retaining parts which are connected continuously to both the side plates, and bonded parts in which bonded plates, connected continuously to the respective shape-retaining surfaces, are folded along lines extended from vertexes of the shape-retaining surfaces on both sides, so that inner surfaces can be bonded together. Paired cut tapes P having tearability are bonded together in parallel on the backside of the front plate 11, and notches 4 are provided in positions inside the cut tapes P near ends of the front plate 11, respectively; or the cut tapes P having the tearability are bonded together on the backside of the front plate 11, and the paired notches 4 are provided in the positions inside the cut tapes P near the ends of the front plate 11.
