Title:
PROTECTIVE ELEMENT AND BATTERY MODULE
Document Type and Number:
WIPO Patent Application WO/2015/107633
Kind Code:
A1
Abstract:
Provided is a protective element for improving the rated capacity of a soluble conductor, and making quick fusing of the soluble conductor possible. The protective element is equipped with an insulating substrate (11), a heating resistor (14) formed on the insulating substrate (11), an insulating member (15) for covering the heating resistor (14), first and second electrodes (12) layered on the insulating substrate (11), a heating-element extraction electrode (16) electrically connected to the heating resistor (14) on the current path between the first and second electrodes (12), and layered on the insulating member (15) so as to overlap the heating resistor (14), a soluble conductor (13) for fusing the current path between the first and second electrodes using heat, and layered from the heating-element extraction electrode (16) to the first and second electrodes (12), and a cover member for covering the insulating substrate (11). Furthermore, the soluble conductor (13) is formed in a manner such that a center section (13a) thereof overlapping the heating-element extraction electrode (16) is thicker than a fusing section (13b) between the heating-element extraction electrode (16) and the first and second electrodes.
