PROBLEM TO BE SOLVED: To provide a paper-drawn tray capable of preventing liquid from leaking and liquid inclusion sealing when sealing a lid material while maintaining the conventional features of easy formability, low cost and lightweight structure. SOLUTION: In the paper-drawn tray, rules given to a drawn portion in advance are divided into a side wall part rule 31B and a flange part rule 31A. The side wall part rule 31B directed from a bottom part 11 to a flange part 15 is divided in front of the flange part, and the flange part rule 31A is deviated in the transverse direction from an extension line of the side wall part rule 31B. In addition, the division position on the flange side of the side wall part rule 31B is substantially the same as the position on the side wall side of the flange part rule 31A. In addition, a portion having no rule is provided between the division position on the flange side of the side wall part rule 31A and the position on the side wall side of the flange part rule, and a rule 43 for liquid storage is provided at the position connecting the flange side division positions of a plurality of the side wall part rules.
