Zusammenfassung:	To provide a manufacturing method of an irregularly shaped polarizing plate high in productivity without causing axis deviation.SOLUTION: The manufacturing method of an irregularly shaped polarizing plate includes at least the steps of: producing an irregularly shaped sheet polarizing plate intermediate body for cutting processing from a long or sheet-like polarizing plate; and processing the obtained irregularly shaped sheet polarizing plate intermediate body by cutting. The irregularly shaped sheet polarizing plate intermediate body has at least one linear outline portion. Under assumption of a rectangle circumscribed with the irregularly shaped sheet polarizing plate intermediate body, the linear outline portion is a part of a side of the rectangle.SELECTED DRAWING: None 【課題】生産性が高く、軸ズレが起きない異形偏光板の製造法を提供することである。【解決手段】異形偏光板の製造方法であって、少なくとも、長尺状またはシート状偏光板から切削加工用の異形枚葉偏光板中間体を作製する工程と、得られた前記異形枚葉偏光板中間体を切削加工する工程を含み、前記異形枚葉偏光板中間体が一箇所以上の直線状の外形部を有し、該直線状の外形部が、前記異形枚葉偏光板中間体に外接する矩形を想定した時、該矩形の１辺の一部であることを特徴とする、異形偏光板の製造方法。【選択図】なし
