Abstract: Provided is a tip capable of repeatedly regenerating a single-atom termination structure in which a distal end is formed of only one atom. A tip (1) having a single-atom termination structure includes: a thin line member (2) made of a first metal material; a protruding portion (4) made of a second metal material, which is formed at least in a distal end portion (2a) of the thin line member (2), and has a distal end terminated with only one atom; and a supply portion (5) made of the second metal material to be supplied to the protruding portion (4), which is formed in the vicinity of the distal end portion (2a) of the thin line member (2).
