PROBLEM TO BE SOLVED: To provide a chip resistor capable of securely preventing cracking, wire breaking, etc., caused by thermal stress of a solder joint part.SOLUTION: A chip resistor 1 comprises: a ceramic substrate 2 in a rectangular parallelepiped shape; a pair of top electrodes 3 provided at both lengthwise ends of a top surface of the ceramic substrate 2; a resistance body 4 connecting both the top electrodes 3 together; a protection layer 5 covering the resistance body 4; a pair of reverse electrodes 6 provided at both lengthwise ends of a reverse side of the ceramic substrate 2; an end face electrode 7 electrically connecting the top electrodes 3 and reverse electrodes 6 to each other; an external electrode 8 covering the end face electrode 7; and a pair of insulating resin layers 9 provided to cover edge part sides of the reverse electrodes 6, the pair of insulating resin layers 9 facing each other at a predetermined interval on the reverse side of the ceramic substrate 2l, and end parts, at least mutually opposite sides, of those insulating resin layers 9 being exposed from the external electrode 8.SELECTED DRAWING: Figure 1 |
