<p>The purpose of the present invention is to provide an electrostatic protective component and a method for manufacturing the same whereby it is possible to form at low cost a front electrode capable of withstanding electrostatic discharge tests (contact discharge tests) for 500 times or more and maintaining the electrostatic discharge suppression peak voltage below 500 V. For this purpose, an electrostatic protective component (100) is configured with front electrodes (2a, 2b) which are formed on a ceramic substrate (1) and are opposite each other via a gap (4a), glass films (21a, 21b) which are formed on the front electrodes so as to cover the upper surfaces (2a-3, 2b-3) and both side surfaces (2a-4, 2b-4) of the front electrodes and are opposite each other via a gap (4b) communicating with the gap (4a), and an electrostatic protective film (5) which has a center portion (5c) and two side portions (5a, 5b) such that the center portion (5c) is provided at the gaps (4a, 4b) and both side portions are overlapped onto the upper surfaces (21a-2, 21b-2) of the glass films, and the material of the front electrodes is a copper-nickel film or a copper-nickel-silver film.</p> |
