Incidentally, the depth D of the groove 13 is about 7 mm, and the width W of the groove 13 is about 6 mm.

  When the cooking cutting board is placed on a table or the like in such an unfolded state P, the entire flexible sheet 7 is brought into use in contact with the table or the like. At that time, if the magnet 8 is attracted to a mounting surface such as a table or a storage shelf or a vertical wall surface, the cooking cutting board can be reliably held.

  When the flexible knob 12 is lifted in the unfolded state P of the cooking cutting board, as shown in FIGS. 3 (a) and 3 (b), the central partition plate 1 and the both side partitions are separated by the weight of the both side partition plates 2 and the both end partition plates 3.
