Abstract
A functional substrate is produced by forming a diffusion source for fabricating an electronic part in a ceramic substrate which has been made semiconductive by a sintering and subjecting the ceramic substrate to a firing to give plural electronic-part-forming units, isolated from one another, in the ceramic substrate. An electronic circuit comprises the functional substrate and at least electrodes for the electronic-part-forming units.
