、必然的に大型なものとならざるを得ない。[Prior art and its problems] Conventionally, copper plates or aluminum plates have been generally used as current busses, but since these have electrical resistance, heat generation is unavoidable. For this reason, generally 2 to 3
Only a current of about A/#2 can flow, and if a large current of several thousand A is to be supplied, a conductor with a large cross-sectional area is required, and the conductor must inevitably be large.

They can be obtained by firing a mixed powder of oxides, carbonates, etc. of each constituent element in stoichiometric amounts giving the above formula. In carrying out the present invention, a base metal plate, for example, CuNi, Nb, or Ti, is prepared by kneading the mixed powder and a solvent.

A mixture of fine powders of BaCO3 and Cu2O in a ratio of 1=1.7:1.9 was calcined at 900°C for 24 hours in an atmosphere with an oxygen partial pressure of 1/10ata, and then the powder was mixed with a particle size of 10μ. The following fine particles were ground and water was added to form a slurry, which was applied to Plate 1. After drying this, it was formed by firing at 1100'C for 30 minutes.
