Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an acrylic resin sheet that has a fragment shape with roundness in breaking while maintaining transparency.SOLUTION: The acrylic resin stretched sheet is a transparent sheet that comprises an acrylic resin having a mass-average molecular weight of 200,000-1,000,000, is simultaneously biaxially stretched twice-20 times by an area ratio in comparison with an area before stretching and has thickness of 0.5-5 mm. The acrylic stretched sheet has a curvature C value of crack defined by formula (1): C=L1/L2 (wherein C is the curvature of crack; L1 is the length measured along crack from a crack generation point to a crack vanishing point; L2 is the straight line distance from a crack generation point to a crack vanishing point) of ≥1.1 when broken by a du Pont falling weight impact test.
