If the solid content concentration of the ink composition is less than 5% by mass, the conductivity of the obtained metallic material may be reduced due to insufficient thickness of the deposited cured product of the ink composition after firing. Therefore, it is not preferable. Further, if the solid content concentration is more than 80% by mass, the ink properties such as viscosity and surface tension of the ink composition are deteriorated, and it is difficult to use as an ink. Additives, organic binders, and the like can be added to the ink composition as appropriate according to the intended use.

- a pH exceeding 3 is not preferable because hydrogen copper fine particles cannot be obtained and may become metal copper fine particles. Since the copper hydride fine particles can be generated in a short time, the pH is particularly preferably 1-2.
- the above reducing agent is preferably added in an equivalent number of 1.5 to 10 times the copper ion. Yes. If the amount of the reducing agent added is less than 1.5 times the number of equivalents to copper ions, the reducing action is insufficient, which is not preferable.

- the above-mentioned organic chemicals containing an amino group are particularly preferable in view of excellent dispersion stability and conductivity of the conductive film after firing.
- the reason is that the adsorption of the amino groups on the surface of the fine particles is strong and has an excellent anti-aggregation effect, and a non-conductive metal compound such as a sulfate is formed after firing like a mercapto group. This is because there is nothing to do.
- the protective agent is appropriately selected depending on the application of the ink composition to be used, but it is preferable to add 5 to 300 parts by mass with respect to 100 parts by mass of the fine particles.
- the amount When the amount is too large, it remains in the metal film even after firing, which becomes an impediment to the conductivity of the conductive metal film.
