Claim 13:
14. The method according to claim 13, wherein in the processing the single crystal material, the single crystal nanowire is thinned toward the end, and the radius of curvature rw of the tip of the end is set to a value of 50% or less of the length dw of the single crystal nanowire in the lateral direction, by setting irradiation conditions of the focused ion beam such that a current is 20 to 100 pA, a voltage is 2 to 10 kV, a position to be irradiated is moved scanning in a direction from an outer side to an inner side of the single crystal nanowire, and irradiation time is 0.5 to 5 minutes.
