Abstract

The element according to the present invention has a first plane () and a second plane () forming a prescribed angle with the first plane. The second plane is provided with at least three portions for position determination (AB,C,D) arranged on the second plane sufficiently spaced apart from each other, allowing the identification of the second plane. Each portion for position determination is formed in a convex shape with respect to the second plane. A tangential plane (TL) to the surface of each portion for position determination at a point on a border line between the second plane and the surface forms a single plane and tangential planes of the portions for position determination are parallel to one another.
