Patent ID: 8173050

Claim:
A conductive pattern formation ink for forming a conductive pattern by ejecting the ink in the form of liquid droplets on a surface of a ceramic molded body using a liquid droplet ejecting method, the ceramic molded body being made of a material containing ceramic particles and a binder, the ink comprising: a water-based dispersion medium; metal particles dispersed in the water-based dispersion medium; and a polyglycerin dispersed in the water-based dispersion medium, the polyglycerin having a weight average molecular weight in the range of 300 to 3,000, wherein the water-based dispersion medium contains oxygen molecules and nitrogen molecules, and wherein when the water-based dispersion medium is analyzed using a gas chromatography method, a total amount of the oxygen and nitrogen molecules contained in the water-based dispersion medium is 12 ppm or less, wherein each of the metal particles has a dispersant adsorbed on the metal particle, the dispersant constituted of a hydroxyl acid or a salt thereof, and the hydroxyl acid and the salt each having three or more COOH and OH groups in a total number, and wherein a number of the COOH groups is equal to or greater than a number of the OH groups.
