CERAMIC BOARD, MANUFACTURE THEREOF AND SPLIT CIRCUIT BOARD

摘要

PROBLEM TO BE SOLVED: To enhance reliability in the connection of end face electrode and an insulating base body by preventing the end face electrode from stripping at the time of handling a split circuit board. SOLUTION: The ceramic board comprises an insulating basic body 13 comprising a laminate of a plurality of ceramic insulating layers, an inner wiring formed between the insulating layers, split grooves 7 made in the surface of insulating basic body 13 and a conductive member 21 for forming an end face electrode 2 provided in the thickness direction of insulating basic body 13. The insulating basic body 13 is split along the split grooves 7 to produce split circuit boards 1 each having a plurality of end face electrodes 2. The conductive member 21 has substantially U-shape and the conductive member 21 of adjacent split circuit boards 1 are disposed on the opposite sides of the split groove 7 at a predetermined interval while facing each other.
