Document Type and Number:
WIPO Patent Application WO/2019/181974
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide, in particular, a chip resistor which can disperse hot spots and reduce adverse effects on characteristics, caused by microcracks. This chip resistor (1) is characterized in having an insulating substrate (2), a resistor (3), and electrodes (4, 5), and in that: the resistor has formed therein a first trimming groove (11) and a second trimming groove (12); a first vertical groove (11a) of the first trimming groove and a second vertical groove (12a) of the second trimming groove are formed in the X1-X2 direction with a gap therebetween; and a first lateral groove (11b) of the first trimming groove and a second lateral groove (12b) of the second trimming groove extend in directions towards each other, and respective terminal ends (11c, 12c) of the first lateral groove and the second lateral groove are formed separated in the X1-X2 direction so as to not overlap in the Y1-Y2 direction.
