Abstract
A wiring board used for mounting an LED bare chip capable of firmly bonding the LED bare chip and improving yield. In a printed wiring board, a distance D between wiring patternsanddisposed so as to oppose each other is the smallest at a position nearest to a center point (G) of an LED chipdisposed at a designed location, and increases with an increasing distance from the point G. In addition, pattern edgesandof the wiring patternsandrecede in the direction of widening the distance D as a distance from the center point G increases with respect to electrode edgesandof the LED chip
