摘要：

An object is to provide a lumen passability checking device that can definitely maintain a capsule shape for a predetermined time necessary to confirm patency. A soluble portion 41 provided in a first insoluble portion 42, which maintains the capsule shape, is divided with an insoluble portion 63 to form a dissolution route 62 that progresses from a part of a surface to inside. By forming the dissolution route 62 longer, a time taken by the soluble portion 41 to dissolve in the lumen is structurally made longer, which maintains the capsule shape for an extended time.
