PROBLEM TO BE SOLVED: To provide a wiring board which can effectively prevent the cracking of its insulating substrate that may cause the stripping off, disconnection, etc., of wiring conductors and is formed by firmly sticking the wiring conductors to the insulating substrate in a prescribed pattern. SOLUTION: A wiring board is constituted by integrally forming wiring conductors 2 in and on an insulating substrate 1 composed of a sintered ceramic body. The corner sections (c) of the wiring conductors 2 formed in the insulating substrate 1 are rounded to circular-arcuate shapes. |
