WIRING BOARD AND METHOD FOR MANUFACTURING LIGHT-EMITTING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide: a wiring board arranged so that the discoloration of a porous substrate owing to metal ions going into pores of the substrate can be suppressed more reliably; and a method for manufacturing a light-emitting device.SOLUTION: A method for manufacturing a wiring board comprises the steps of: coating a porous ceramic substrate (10) with a pretreatment liquid (11) which forms a permeation-preventive film (12) for closing pores of the porous ceramic substrate, but is decomposed by baking; forming the permeation-preventive film on the porous ceramic substrate by curing the pretreatment liquid; forming wiring (13) on a surface of the porous ceramic substrate with the permeation-preventive film formed thereon; and baking the porous ceramic substrate with the wiring formed thereon at a temperature which causes the decomposition of the permeation-preventive film.SELECTED DRAWING: Figure 2
