Patent ID: 7262489

Claim:
A three-dimensionally formed circuit sheet comprising: a resin film originally being in a flat sheet, and a circuit pattern formed of an electrically conductive paste on the resin film, the electrically conductive paste containing, as a binder, a resin that is three-dimensionally formable; wherein the resin contain a thermoplastic aromatic polycarbonate having a weight-average molecular weight of at least 10,000, and containing bifunctional carbonate structure units represented by the following formula (I), wherein R 1 and R 2 independently represent hydrogen, a halogen, C 1-8 alkyl, C 5-6 cycloalkyl, or C 6-10 aryl alkyl; m represents an integer from 4 to 7; R 3 and R 4 independently represent hydrogen or a C 1-6 alkyl, and can be independently selected with respect to each X; X represents at least one carbon atom; and both R 3 and R 4 are alkyl groups; wherein the resin film and the circuit pattern are integrally formed into a three-dimensional shape from the flat sheet.
