Abstract
A laminated variable resistor comprises a main body, internal electrodes extending along two side edges of the main body into the main body, terminal electrodes disposed on the two ends of the main body. The mole percentage of the oxide in overlapping active regions between opposite internal electrodes is reduced and the reduced portion is replaced by a metal selected from gold (Au), silver (Ag), palladium (Pd), platinum (Pt), rhodium (Rh), or the alloy of any two of such metals.
Claims3
A laminated variable resistor, comprising:
- a main body, including a plurality of internal electrodes respectively extending along two side edges of the main body into the main body, so as to form an overlapping region where one of the internal electrodes overlaps an adjacent electrode;
- two terminal electrodes, disposed on two ends of the main body respectively;
- wherein the overlapping region includes at least a metal oxide grain and a metal grain.
