PROBLEM TO BE SOLVED: To provide a raisable case made of paper which can be prevented from moving transversely when being piled up in layers, can be easily held, and can protect articles housed therein. SOLUTION: Projecting leg parts 36 are provided respectively at four corners of a bottom board part 11, each of the projecting leg parts 36 has first and second leg pieces 43 and 44 which are separated from the bottom board part 11 respectively by a first incision 39 which connects the end of a first crease 12 with the end of a second crease 13 and a second crease 42 which connects the corner 45 of the bottom board part 11 with the first incision 39, and each of external wall parts 16-19 is formed in a trapezoidal shape expending gradually in width toward the side connected to the bottom board part 11, and when the case is raised and a plurality of the raised cases are piled up in vertical layers, the external upper edges 48 of the external wall parts 16-19 are fitted virtually into the inside of the projecting leg parts 36 formed at the four corners of the bottom board part 11 of the case in the upper layer laid on the external wall parts 16-19.
