ACTIVE ENERGY RAY-CURABLE ELECTROCONDUCTIVE PASTE, AND CONDUCTOR CIRCUIT AND NON-CONTACT ID USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electroconductive paste which can be applicable to a base material having poor heat resistance and needs a very short time for a curing process in the manufacture of a conductive circuit so that it realizes high mass productivity of conductive circuits and is effective for reducing the production cost of a non-contact ID. SOLUTION: There is provided an electroconductive paste comprising an electroconductive substance and active energy ray-polymerizable compound which gives a cured film having an internal stress of 5-50 MPa when cured by an electron beam having an accelerated voltage of 150 kV at an irradiation dose 40 kGy. A method for manufacturing a conductive circuit comprises a step of forming a circuit pattern on a substrate using the electroconductive paste and irradiating it with an active energy ray. The conductive circuit is manufactured by such process. The non-contact ID is prepared by mounting the conductive circuit and an IC chip on a substrate.
