PROBLEM TO BE SOLVED: To provide an index with a foot that can be formed at low cost, can form even a thick and complex shape, and has large mounting strength. SOLUTION: Electrocasting plating is performed by providing a conductive metal film 51 in an electrocasting mother die 40, that is made of resin and has a recess 41 for forming the shape of the index; metal is deposited at the recess 41 for forming a primary index blank 50A; the primary index blank 50A and the electrocasting mother die 40 are subjected to grinding machining or cutting machining; a secondary index blank 50B, in which a rectangular foot 52b is provided is formed at the primary index blank 50A; then, the secondary index blank 50B is peeled from the electrocasting mother die 40; and the secondary peeled index blank 50B is subjected to finishing plating and an index with foot is obtained.
