厚い線を描かなければならないという欠点があった。(Prior Art) Conventional conductive paste materials are usually made by mixing fine powder of metals such as Au, Ag, Cu, or graphite with resins such as epoxy resins, and diluting the mixture with a solvent such as methyl ethyl ketone. However, although Au and Ag have good conductivity, they are expensive, and Cu suffers from poor characteristics due to surface oxidation (decrease in ρ).
Graphite with a large diameter has the disadvantage that thick lines must be drawn to obtain the desired conductivity.
