PROBLEM TO BE SOLVED: To provide an inexpensive ceramic wiring board which can reduce the mounting area, the thermal stress, and can be visually checked, and to provide its manufacturing method. SOLUTION: The ceramic wiring board 10 is equipped with a plurality of external connection terminals 11 of conductive metal which are formed together with a ceramic sheet by baking on its one main surface and surface-mounted on a mounting board 13 using the external connection terminals 11. An undercut is provided on the main surface of the ceramic wiring board 10 to produce a level difference 15 receding inward from the peripheral edge of the one main surface of the wiring board 10, and the side 16 of the level difference 15 is coated with conductor metal to serve as the external connection terminal 11.
