A metal ink containing metal particles including silver, a protective agent A including an amine compound, and a protective agent B including a fatty acid. The metal ink is configured such that the protective agent A includes at least one C4-12 amine compound, and the protective agent B includes at least one C22-26 fatty acid. It is preferable that the amine compound content is 0.2 mmol/g or more and 1.5 mmol/g or less on a silver particle mass basis. In addition, it is preferable that the fatty acid content is 0.01 mmol/g or more and 0.06 mmol/g or less on a silver particle mass basis.
