Abstract
A conductive pattern formation ink which can be stably ejected in the form of liquid droplets and form a conductive pattern having high reliability, a conductive pattern having high reliability, and a wiring substrate provided with the conductive pattern and having high reliability are provided. The conductive pattern formation ink is used 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 contains a water-based dispersion medium, and metal particles dispersed in the water-based dispersion medium, 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.
