には非常に不都合なものである。Conventionally, a non-contact type data transmitter / receiver for exchanging data in a non-contact manner, for example, as called an IC tag, has an IC mounted on an antenna disposed on a base material.
A predetermined circuit is formed by mounting a chip. When forming the antenna, the base material is a sheet made of a synthetic resin, and a conductive ink is printed on the base material using a printing method, and the base material is cured. The conductive ink is a thermosetting conductive material. If you select an ink and use infrared rays, the conductive ink will be heated to a high temperature in a short time,
The conductive ink can be cured in a shorter time than when a heat drying oven is used. However, it is difficult to control the temperature due to rapid heating in a short time, and when a sheet made of a resin such as polyethylene terephthalate having a heat deformation temperature of 200 ° C. or lower is used as a base material, the resin shrinks (that is, the base material is shrunk). Shrinks)
This is very inconvenient for circuit formation such as mounting electronic components.

ものである。Further, when paper is used as a base material, the degree of shrinkage due to the application of heat may be small, but the conductive pattern becomes hotter than the base material, and the base material is placed on the back surface corresponding to the conductive pattern. The phenomenon that discoloration of the material occurs has been confirmed. When a near-infrared ray is irradiated from the back surface onto the substrate (paper) coated with the thermosetting conductive ink,
It has been confirmed that the degree of discoloration on the back surface is small, but it is not sufficient. In addition, intermittent heating has been proposed, but there was a problem that temperature control was difficult and discoloration occurred in the paper base material. In view of the above circumstances, an object of the present invention is to suppress discoloration due to heat while ensuring the usefulness of paper as a base material, and an object of the present invention is to enable an appropriate conductive pattern to be formed. .
