PROBLEM TO BE SOLVED: To provide an electronic component capable of improving the junction strength between a terminal electrode and a protruding electrode. SOLUTION: The electronic component 1 includes a substratum 3, the terminal electrode 5, an insulating layer 7, and the protruding electrode 9. The terminal electrode 5 is formed on the substratum 3. The insulating layer 7 is formed on the substratum 3 and the terminal electrode 5 to have at least part of the electrode 5 exposed. The protruding electrode 9 is formed on the terminal electrode 5 and is made of solder. A plurality of through-holes 13 up to the terminal electrode 5 are formed on the insulating layer 7, at a rim 8 closer to a part 6 of the electrode 5 exposed from the insulating layer 7. The protruding electrode 9 is positioned on the rim 8, so that a part of it covers the rim 8 and connected with to terminal electrode 5 through the plurality of through-holes 13.
