The present invention addresses the problem of providing a device for spreading shapeable thin items that is capable of spreading shapeable thin items using a simple configuration. In the device for spreading shapeable thin items: a control unit controls a gripping unit and a travel mechanism such that the gripping unit grips a shapeable thin item at a first point (S1); the control unit makes an end point detection unit detect an end point (S3); the control unit controls the gripping unit and the travel mechanism such that the gripping unit holds the shapeable thin item at the end position detected in S3 (the first end point) (S4); the control unit makes the end point detection unit detect the end point (S6); the control unit controls the gripping unit and the travel mechanism such that the gripping unit holds the shapeable thin item at both the first end point and the end point detected in S6 (the second end point) (S7); the control unit makes the end point detection unit detect the end point (S9); and the control unit controls the gripping unit and the travel mechanism such that the gripping unit holds the shapeable thin item at both either the first end point or the second end point and the end point detected in S9 (S10).
