PROBLEM TO BE SOLVED: To provide an element component of a magnetic accessory, a component that is suitable for a magnetic accessory requiring no through string or connection fixture, that is free from breaking, cracking or rusting due to impact at suction coupling, and that has high magnetic resistance in a connection part, fully generating leakage flux effective for magnetic treatment from the connection part.SOLUTION: This is a columnar collection in which a columnar piece composed of a rare earth magnet magnetized in a prescribed direction is inserted into the center hole of a cylindrical piece that is nearly the same length as or longer than the columnar piece and in which both end openings of the center hole of the cylindrical piece are sealed with a sealant. The magnetizing direction of the rare earth magnet is designed such that, when the plurality of collections are arranged in the same direction, a magnetic attraction works between the adjacent collections.
