PROBLEM TO BE SOLVED: To provide a multipiece wiring board in which wiring boards formed as a plurality of vertical and horizontal arrays and having high reliability of electrical connection can be produced on a ceramic mother board having extremely thin thickness, and a wide area and wiring boards having no notch, crack or the like can be surely formed. SOLUTION: The multipiece wiring board is provided with a ceramic mother board 2 on which a plurality of vertical and horizontal arrays of wiring board areas 1 are formed, a plurality of wiring conductors 3 formed through the wiring board areas 1 and electrodes 4 formed on a pair of end faces of the ceramic mother board 2 and electrically connected to the wiring conductors 3. Each electrode 4 consists of a metalized layer 6 coated on the whole inner surface of a notch part 5 formed on each of a pair of end faces of the ceramic mother board 2 and the notch part 5 consists of a 1st notch 5-1 and a 2nd notch 5-2 formed by further notching the center part of the 1st notch 5-1.
