To provide a chip network electronic part in which the angle between a face and a bottom is set to a specific angle or larger thereby preventing production of a microcrack in the contacting part.

In a chip network device in which a plurality of resistor devices 2 are provided on the surface of a substrate 1, a plurality of recessed parts each constructed by a pair of faces 8A, 8A and a bottom part 8B connecting the faces 8A, 8A are formed on the outer circumference, and projecting parts 9 between the faces 8A, 8A are used as electrodes, the angle between the face 8A and the bottom part 8B is set to 90°C or larger. A distance P2 between the faces 8A, 8A is set to value smaller than about 0.5. The width P1 of the electrode 9 is set wider than the distance P2 and is set to a value as wide as possible, thereby reducing the influence of a crack. Thus, occurrence of the breakage of the electrode 9 caused by microcracks can be suppressed.
