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.
Claims7
A resistor comprising:
- a resistive element made of a metal plate;
- a protective film formed on a first surface of the resistive element;
- and
- a pair of electrodes separated from each other with the protective film therebetween and formed at both ends of the first surface of the resistive element,
- wherein the pair of electrodes are formed by printing paste containing resin and metal powder contained in the resin.
A method of manufacturing a resistor, the method comprising:
- forming a plurality of electrodes by printing metal powder-containing paste at space intervals on an upper surface of a resistive element made of metal plate;
- forming a protective film so as to cover the upper surface of the resistive element and upper surfaces of the electrodes;
- and
- grinding the protective film until the electrodes are exposed.
A method of manufacturing a resistor, the method comprising:
- forming a resist on an upper surface of a sheet-shaped resistive element made of metal;
- forming a plurality of belt-shaped spaces in the resist;
- forming belt-shaped electrodes on the upper surface of the sheet-shaped resistive element by printing metal paste in the spaces;
- removing the resist;
- forming an insulating film so as to cover a part, which is exposed from the belt-shaped electrodes, of the sheet-shaped resistive element;
- and
- cutting the sheet-shaped resistive element with the belt-shaped electrodes and the insulating film into individual resistive elements,
- wherein an exposure mask having a plurality of belt-shaped openings is placed on the resist, and the resist is exposed through the exposure mask and removed partially in the shape of belts when forming the belt-shaped spaces in the resist.
