Beschreibung
Zusammenfassung:	An elastic roll having high chemical-solution resistance and enabling roll hardness to be optimized is provided. With this elastic roll, a nip roll and a conveyance device that can be used for a long period of time even under environments in which a chemical solution adheres thereto are provided. An elastic roll of the present invention includes: a roll core; an inner-layer laminate covering an outer-peripheral surface of the roll core parallel to a roll longitudinal direction; a surface-layer elastomer including a tubular portion covering an outer-peripheral surface of the inner-layer laminate and edge portions connected to the tubular portion, covering both end surfaces of the inner-layer laminate orthogonal to the roll longitudinal direction, and arranged in a manner being in contact with the roll core; and end-portion sealing structural bodies configured to press the edge portions of the surface-layer elastomer against the roll core.
