Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ER element and an ER device using the same, using the electric rheology (ER) gel, not breaking a gel structure even when shearing displacement is given to the ER gel, and high shearing stress can be produced. SOLUTION: In this ER element 10 wherein the ER gel 20 is placed between a pair of electrodes 11, non-immobilizing treatment is performed on at least one of the electrodes 11 and the ER gel 20. The non-immobilizing treatment is performed by covering the surface of the electrode with a mold-releasing agent, or applying a lubricant onto the surface of the electrode. An ER effect can be effectively utilized by controlling the maximum height roughness (Rz), defined by JIS Z0601, of the surface of the electrode at a non-immobilized treatment side, to 1-0.001 mm, and the average length (RSm) of a rough curve element to 5-0.001 mm.
