PURPOSE: A keeper for a dental magnetic attachment is provided to reduce the production costs, to enhance the detachment prevention effect, and to offer the keeper with a high strength. CONSTITUTION: The keeper(1) for a dental magnetic attachment, which sticks the magnetic structural body to a denture, includes: a keeper body(10) of a plate shape; and a route(2), arranged on the bottom of the keeper body(10). The keeper body(10) and the route(2) are made out of the same soft magnetic material and manufactured as a one body by being worked out of a single soft magnetic material. The route(2) has a small diameter portion(21), connected to a large diameter one(22), and the outer diameter of the large diameter portion(22) is greater than that of the small diameter portion. The small-diameter portion(21) is connected to the bottom of the keeper body(10).
