ABSTRACT:
A process for producing a ceramic member having fine throughholes, includes a step of preparing a first green sheet for a thin ceramic plate, a step of forming, in the first green sheet, a plurality of fine throughholes so that the hole-to-hole distance after sintering becomes 70 .mu.m or less, a step of preparing a second green sheet for a ceramic substrate, a step of forming at least one window in the second green sheet, a step of laminating the first green sheet having a plurality of fine throughholes, on the second green sheet having at least one window so that the plurality of fine throughholes correspond to the at least one window, to form a unitary laminate, and a step of sintering the laminate to produce a unitarily sintered material as a ceramic member having fine throughholes. Alternatively, the throughholes can be formed after the first and second sheets are laminated.
