Provided is a method of manufacturing a ceramic multi-layer circuit substrate. A plurality of ceramic blocks, in each of which one or more ceramic green sheets having via-electrodes are layered one atop the other, are formed and are then fired. The fired ceramic blocks are aligned with each other. One or more bonding green sheets each having bonding electrodes in positions corresponding to the via-electrodes of the ceramic blocks are prepared. Each of the bonding green sheets is interposed between a pair of the ceramic blocks opposing each other. The ceramic blocks and the bonding green sheets are bonded and are then fired.
