A sintered body, for manufacturing a ceramic substrate, on which a via can be formed with high positional accuracy and the substrate is not warped and further the productivity is high. The sintered body includes a pillar-shaped ceramic body and metallic wiring rods provided in the ceramic body in parallel with the axis. The metallic wiring rods are made of metal, the melting point of which is lower than the sintering temperature of the sintered ceramic body. |
