Abstract

A conductive pattern production device includes: a patterning unit that forms a pattern of a composite ink on a base member; and a burning unit that burns the pattern by high-frequency heating. The composite ink is obtained by mixing a particle material that is a material having a relative permeability of 200 or above or a carbon micro-coil and a conductive ink that has, after the burning, a resistivity of 1 to 2000 μΩ·cm.

First claim

What is claimed is:

1. A conductive pattern production device comprising:
a pattern applicator that forms a pattern of a composite ink on a base member; and
a burner that burns the pattern by heating,
wherein the composite ink is obtained by mixing a particle material that is a material having a relative permeability of 200 or above or a carbon micro-coil and a conductive ink that has, after the burning, a resistivity of 1 to 2000 μΩ·cm, and
wherein the pattern applicator comprises:
a first pattern applicator that applies one of the particle material and the conductive ink; and
a second pattern applicator that applies the other of the particle material and the conductive ink.

2. The conductive pattern production device according to claim 1 ,
wherein the pattern applicator forms, as the pattern of the composite ink, a pattern in which the particle material and the conductive ink are stacked in layers.

3. The conductive pattern production device according to claim 2 ,
wherein the first pattern applicator applies the particle material onto the base member; and
the second pattern applicator applies the conductive ink onto the applied particle material.

4. The conductive pattern production device according to claim 1 , wherein the particle material is a carbon micro-coil.

5. The conductive pattern production device according to claim 1 , wherein the particle material is any of Ni, Co, Fe and Gd.

6. The conductive pattern production device according to claim 1 , wherein the burner generates electromagnetic waves of 300 MHz to 300 GHz.

7. The conductive pattern production device according to claim 1 , wherein the burner is a magnetron, klystron, gyrotron, or microwave heater.

8. The conductive pattern production device according to claim 1 , wherein the pattern, applicator comprises anon-plate printing head, dispenser, or plate printing head.

9. The conductive pattern production device according to claim 8 , wherein the plate printing head is a screen printing, gravure printing or flexographic printing head.
