PROBLEM TO BE SOLVED: To provide a ceramic wiring board for multiple units, capable of accurately dividing a ceramic base board along notches by mutually and electrically connecting respective metallized wiring conductors in respective wiring board areas formed on the ceramic base board, through connecting metallized conductors crossing the boundaries of the wiring board areas and forming the notches having sufficient depth on the boundaries of respective wiring board regions. SOLUTION: The notches 6 are formed on the upper surface and/or lower surface of the ceramic base board 1 in depth of up to the connecting metallized conductors 4, the cross-section of the notch 6 is an approximately V-shape in a part shallower than the conductor 4, and both sides of the notch 6 are brought into contact with each other in the conductor 4.
