A PTC device, which reduces the potential of an electrical connection of a solder connection formed to be connected to a substrate from becoming defective as much as possible, is provided. The PTC device comprises a PTC element having: a PTC unit comprising a layered PTC component and a first layered electrode and a second layered electrode, which are each positioned on a surface on either side of the layered PTC component; and insulating layers positioned on the outside of each layered electrode. The PTC element has a first end and a second end, and, at the first end, has a first quarter cylindrical recess in each corner, and at the second end, has second quarter cylindrical recesses in the corners.
