Abstract
Disclosed is a chip network electronic component prevents a short circuit between adjacent electrodes upon soldering, and the strength of the projecting portion is increased to improve reliability. The chip network electronic component includes an insulator substrate having recessed portions in opposite side surfaces to have a plurality of pairs of projecting portions. Electrodes are formed respectively at the projecting portions so as to extend from a main surface to a back surface of the substrate. Electrical elements are each formed on the main surface of the substrate to electrically connect between one pair of the electrodes. A coating layer covers a surface of the electrical elements. The recessed portion includes a pair of opposite flat planes and a flat-planed bottom connecting between the flat planes. The flat plane and the bottom has a connecting portion formed therebetween to have a curvature of 0.1 mm or greater.
