ELECTROCONDUCTIVE INK, ELECTROCONDUCTIVE CIRCUIT, AND CIRCUIT ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide an electroconductive ink whose resistivity is to be increased markedly by applying thereon a definite temperature, and to provide an electroconductive circuit which is printed with a usual printing method by using the same, and whose resistivity is to be increased markedly by applying a definite temperature on the printed matter.

SOLUTION: This electroconductive ink contains: a silver powder which has an average particle diameter of 3-8μm, a specific surface area of 1.5-4.0 m2/g and an apparent density of 0.4-1.1 g/cm3; a binder component; and calcium carbonate with a primary particle diameter of 20-100 nm and of a globular or cubic shape.
