Abstract
A chip resistor (A) comprises a first insulation layer (A) covering the regions between a plurality of electrodes () on a rear surface () of a resistor (), and a second insulation layer covering a pair of side faces of the resistor (). Inadvertent adhesion of solder to an improper part of the resistor () can thereby be eliminated. A solder layer () is preferably formed on a pair of end faces () of the resistor (). In so doing, a solder fillet can be formed appropriately.
