Abstract
A method of manufacturing a circuit board includes: forming a plurality of metal electrodes so as to be separated from each other on a holding sheet by cutting a metal foil held on the holding sheet to remove a portion of the metal foil; forming adhesive layers on surfaces of the plurality of metal electrodes; adhering the adhesive layers to a base material by closely contacting the adhesive layers with the base material; and transcribing the adhesive layers and the plurality of metal electrodes onto the base material by detaching the holding sheet from the plurality of metal electrodes.
