## Abstract

A resistor includes a resistive element, a protective film, and a pair of electrodes. The resistive element is made of a metal plate. The protective film is formed on the upper surface of the resistive element. The plated layers are formed to cover the electrodes. The electrodes are separated from each other with the protective film therebetween and are formed at both ends of the upper surface of the resistive element. The electrodes are formed by printing metal-containing paste.

## Claims

### Claim 1

A method of manufacturing a resistor, the method comprising:
forming a plurality of belt-shaped electrodes by printing metal powder-containing paste at space intervals on a surface of a sheet-shaped resistive element made of metal;
forming, on the sheet-shaped resistive element, a slit crossing the belt-shaped electrodes;
forming a first insulating film between each adjacent two of the belt-shaped electrodes and forming a second insulating film filling the slit; and
dividing the sheet-shaped resistive element into individual resistive elements by cutting the sheet-shaped resistive element along the slit and along the belt-shaped electrodes.
