<p>PROBLEM TO BE SOLVED: To provide a ruled sheet and a case in which the sheet is used, having a good appearance without causing delamination. SOLUTION: A ruled sheet 100 is formed by laminating at least a single layer of intermediate layers 41, 42, 43 between the outermost layers 2, 3 provided on both outsides of the sheet. The layers 2, 3 are each formed of a material having tensile strength higher than the single body of the intermediate layers 41, 42, 43. It is preferable that the rule is formed so as to break at least a part of the intermediate layers 41, 42, 43 without breaking the outermost layers 2, 3. It is preferable that the intermediate layers 41, 42, 43 are each formed of cellophane or polylactic acid.</p> |
