Overcurrent protection element

An overcurrent protection element, comprising:

• a core material comprising a top surface, a bottom surface opposite the top surface, a first side surface and a second side surface both located between the top surface and the bottom surface, and a first end surface and a second end surface both located between the top surface and the bottom surface;
• a first conductive layer formed on the top surface of the core material;
• a second conductive layer formed on the bottom surface of the core material;
• an encapsulation layer covering the first conductive layer, the second conductive layer, and at least one of the first side surface and the second side surface;
• a first terminal electrode electrically connected to the first conductive layer;
• and
• a second terminal electrode electrically connected to the second conductive layer;
• wherein the overcurrent protection element comprises a first insulation film and a second insulation film, the first insulation film is formed on the first conductive layer, and the second insulation film is formed on the second conductive layer;
• wherein the overcurrent protection element comprises a third conductive layer and a fourth conductive layer, the third conductive layer is formed on a surface of the first insulation film, extends between the first terminal electrode and the first end surface, and continuously extends to a surface of the second insulation film, and the fourth conductive layer is formed on the surface of the second insulation film, extends between the second terminal electrode and the second end surface, and continuously extends to the surface of the first insulation film.
