Protecting device and method for manufacturing protecting device

A protecting device, comprising:

• an insulating substrate;
• a heat generator provided on the back surface of the insulating substrate;
• a first electrode and a second electrode provided on the insulating substrate;
• a meltable conductor disposed on surfaces of the first electrode and the second electrode to provide an electrical connection between the first electrode and the second electrode, wherein
• the connection portions of the first electrode and the second electrode connected to the meltable conductor are formed thicker than the other portions.

A method for manufacturing a protecting device, comprising:

• a step of forming a first electrode, a second electrode, and a heat-generator lead-out electrode disposed between the first electrode and the second electrode by printing and baking conductive paste on an insulating substrate;
• and
• a step of forming a connection electrode to be connected to a meltable conductor that connects the first electrode, the second electrode, and the heat-generator lead-out electrode by printing and baking conductive paste on the first electrode, the second electrode, and the heat-generator lead-out electrode, wherein
• the connection portions of the first electrode, the second electrode, and the heat-generator lead-out electrode to be connected to the meltable conductor are formed thicker than the other portions.
