Abstract

Disclosed is an electrostatic protection component that can minimize decreases in insulation resistance following the application of ESD voltage, and can also minimize variations in the insulation resistance of each component. Also disclosed is a production method therefor. The structure of the electrostatic protection component (100) is provided with surface electrodes (2a, 2b) that are formed upon a ceramic substrate (1) and are mutually facing with a gap (4a) therebetween; glass membranes (21a, 21b) that are formed upon the surface electrodes (2a, 2b) and cover the top surface (2a-3, 2b-3) and both side surfaces (2a-4, 2a-5, 2b-4, 2b-5) of the surface electrodes (2a, 2b), and that are mutually facing with a gap (4b) therebetween that connects to the gap (4a); and an electrostatic protection membrane (5) that has a center portion (5c) and side portions (5a, 5b), wherein the center portion (5c) is disposed in the gaps (4a, 4b) and the side portions (5a, 5b) are stacked on the top surface (21a-2, 21b-2) of the glass membranes (21a, 21b).

Description

technical field [0001] The invention relates to an electrostatic protection component and a manufacturing method thereof. Background technique [0002] In recent years, electronic equipment such as portable information equipment has been gradually reduced in size and enhanced in functionality, but the withstand voltage of the electronic equipment has been lowered along with this. Therefore, in electronic devices such as portable information devices, electrostatic protection components are used in order to protect the electronic devices from overvoltage due to static pulses and external noise. [0003] The electrostatic protection part has surface electrodes facing each other across a gap, and an electrostatic protection film arranged in the gap. In electronic equipment, the electrostatic protection part is arranged between a wire that may be applied with an overvoltage and a ground, and the wire When an overvoltage is applied, a discharge is generated between the surface e...
