Claim Text:
1. A method for manufacturing an ESD protection structure including an insulating portion, a pair of discharge electrodes disposed at a distance from each other on a surface of the insulating portion, and discharge-assisting electrodes disposed dispersedly between the pair of discharge electrodes, the method comprising the steps of: forming electrode layers defining the discharge electrode pair and insulating material-coated metal particles and/or semiconductor particles defining the discharge-assisting electrodes on the insulating portion; firing the insulating portion including the electrode layers and the insulating material-coated metal particles and/or semiconductor particles to form the ESD protection structure; forming a vitreous substance so as to surround the discharge-assisting electrodes during the firing step; applying a voltage exceeding a discharge voltage between the pair of discharge electrodes after the firing step is executed; and forming a discharge crater in or on the vitreous substance by removing a portion of the vitreous substance.
