PROBLEM TO BE SOLVED: To provide a cold insulation storage where distortion or the like due to welding heat in manufacture hardly appears on an outside surface of a cold insulation storage body. SOLUTION: This cold insulation storage is provided, in the cold insulation storage body 1, with a cooling means 3 for cooling the inside of a cold insulation chamber 2. Casters 6 are attached to a bottom surface of the cold insulation storage body 1. A circumferential wall 7 surrounding the cold insulation chamber 2 is formed into a heat insulation structure composed by sandwiching a heat insulation material 10 between an outer box 11 and an inner box 12. The outer box 11 has side plates 16, 17 and 19 attached to a frame body 15. Ends of the side plates 16, 17 and 19 are respectively folded back to the inside of the outer box 11, and the tip sides of the folded-back parts are bent toward the inside of the outer box 11, whereby butted parts 45 are formed at ends of the side plates 16, 17 and 19. For respective poles 26 of the frame body 15, the butted parts 45 of the side plates 16, 17 and 19 and butted parts 49 of the respective poles 26 are respectively butted to each other, and the butted parts 45 and 49 are jointed to each other by seam-welding.
