PTC Device

A PTC device comprising a laminate which comprises:

• a PTC component which comprises a laminar PTC element defined by a first main surface and a second main surface which are facing to each other, a first laminar electrode extending on the first main surface, and a second laminar electrode extending on the second main surface, and
• a first insulation layer which is positioned on the first main surface via the first laminar electrode, and a second insulation layer which is positioned on the second main surface via the second laminar electrode, and in which the first insulation layer, the PTC component, and the second insulation layer are laminated in the listed order,
• wherein:
• the laminate has a first end and a second end with respect to a direction perpendicular to a laminating direction, and a first side electrode and a second side electrode are disposed on the first end and the second end, respectively;
• the first laminar electrode of the PTC component extends while being separated from the first side electrode and the second side electrode;
• the second laminar electrode of the PTC component is separated from the first end, and extends to the second end and is electrically connected to the second side electrode;
• at least the first side electrode extends at the first end along an entirety of a thickness direction of the laminate and further extends on a first edge portion of the first insulation layer;
• and
• the first edge portion has a through-hole which reaches the first laminar electrode, and the through-hole has an electrically conductive element which electrically connects the first laminar electrode and the first side electrode.
