Abstract
A chip resistor includes: a resistor body having a front surface and a mounting surface which face in opposite directions; a pair of electrodes which are disposed on both sides of the resistor body with the resistor body sandwiched therebetween and are in electrical conduction with the resistor body; and a protective film covering a portion of the resistor body, wherein a plurality of grooves, which does not penetrate through the resistor body, is formed in the front surface of the resistor body.

A method for manufacturing a chip resistor, comprising:
- preparing a sheet resistor body which includes a plurality of resistor body regions and has a front surface and a mounting surface which face in opposite directions;
- forming a plurality of grooves for resistance adjustment for each of the resistor body regions, the plurality of grooves being formed in front surfaces of the plurality of resistor body regions and not penetrating through the resistor body regions;
- forming a protective film body covering a portion of the plurality of resistor body regions in the front surface of the sheet resistor body;
- forming a conductive layer in an exposed portion of the plurality of resistor body regions, which is not covered by the protective film body, in the front surface of the sheet resistor body;
- and
- dividing the sheet resistor body into segments for the resistor body regions to form a pair of inner electrodes, which are in electrical conduction with the resistor body regions, on both sides of each of the resistor body regions with the resistor body regions sandwiched between the inner electrodes.
