Title:
CHIP RESISTOR
Document Type and Number:
WIPO Patent Application WO/2019/159775
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a chip resistor that is capable of suppressing occurrence of migration. The chip resistor (10) according to the present disclosure is provided with an insulated substrate (1), a pair of electrodes (2), a resistive element (3), a protective film (4), a pair of end-face electrodes (5), and a plated layer (6). The pair of electrodes (2) include silver provided to one surface of the insulated substrate (1). The resistive element (3) is electrically connected to the pair of electrodes (2), and formed on one surface of the insulated substrate (1). The protective film (4) is formed so as to cover the resistive element (3) and a first region (21) which is part of the pair of electrodes (2). The pair of end-face electrodes (5) cover at least part of a second region (22) which is an area of the pair of electrodes (2) exposed from the protective film (4), and are provided at the two end faces of the insulated substrate (1) so as to be electrically connected to the pair of electrodes (2). The plated layer (6) is formed on the surface of the pair of end-face electrodes (5). The protective film (4) contains an inorganic ion scavenger.
