Abstract

A binder resin for an inorganic particle-dispersed paste that excels in both printability and adhesiveness and such an inorganic particle-dispersed paste are provided. The resin includes a mixture in which a polyvinyl acetal and a cellulose derivative are mixed so as to satisfy 0.2≤X/(X+Y)≤0.8, where X and Y stand for parts by mass of the polyvinyl acetal and the cellulose derivative, respectively. When a paste is formulated by mixing and kneading the resin with spherical nickel particles with an average particle diameter of 0.3 μm, barium titanate particles with an average particle diameter of 0.05 μm, a nonionic surfactant, dihydroterpineol, and mineral spirit at the prescribed mixing ratio, the paste has prescribed rheological characteristics.
