PROBLEM TO BE SOLVED: To provide a PTC element capable of suppressing a connection defect in terminal electrodes, and to provide its manufacturing method. SOLUTION: The PTC element manufacturing method includes a process for arranging a body base material M at a position which is held between opposite regions 121, 141 where the coarse surface sides of the terminal electrodes 12, 14 are partially and mutually opposed, and bringing the terminal electrodes 12, 14 into pressure contact with the body base material M; a process for cutting an extending part M1 by introducing the tip end of a cutting member 40 to a part from the extending part M1 to the inner part of the terminal electrode 14 which is joined with the extending part M1; and a process for forming a notched part 12a by moving the cutting member 40 to at least the end M1a of the extending part M1 at the side of the extending part M1 and also in the extending direction of the terminal electrode 14, in such condition of tip ends of the cutting member 40 guided into inside of the terminal electrode 14.
