PROBLEM TO BE SOLVED: To manufacture a precise bulkhead at a low cost by filling a mixture of ceramic powder or glass powder with a binder to a plurality of grooves cut in a roll, and rotating the roll in contact with a plate material consisting of ceramic or glass. ;SOLUTION: Electrodes 5 are formed at prescribed intervals on one surface of a back plate 2 consisting of ceramics or glass. A paste of a mixture of ceramic or glass powder with a binder is filled in the circumferential grooves 12 of a roll 13 having circumferential grooves of prescribed width and depth formed thereon at prescribed intervals corresponding to the bulkhead. The roll 13 is brought into contact with the back plate 2, and rotated while pressurizing it, whereby the paste filled in the circumferential grooves 12 is raised on the back plate 2 as it keeps the shape of the circumferential grooves 12 to form a bulkhead. Thereafter, the bulkhead is hardened by thermal treatment to provide a substrate. When the roll 13 is preliminarily manufactured with a high precision, a highly precise bulkhead can be easily formed.;COPYRIGHT: (C)1998,JPO
