Provided are a binder resin for inorganic particle-dispersed pastes, said binder resin having both good printing properties and high adhesiveness, and an inorganic particle-dispersed paste. The binder resin for inorganic particle-dispersed pastes is a resin that contains a mixture prepared by mixing X parts by mass of polyvinyl acetal with Y parts by mass of a cellulose derivative in such a manner as to satisfy the requirement 0.2≤X/(X+Y)≤0.8, wherein, when the resin is mixed with spherical nickel particles having an average particle size of 0.3 μm, barium titanate particles having an average particle size of 0.05 μm, a nonionic surfactant, dihydroterpineol and a mineral spirit at a preset ratio and kneaded to give a paste and a strain of 0.02 and a strain of 0.2 are applied to the paste at an angular frequency of 6.284 rad/s, the phase difference value δ caused by the strains and the resultant stresses is larger than 45°, and the ratio of the viscosity at a shear rate of 4 (1/s) of the paste to the viscosity at a shear rate of 40 (1/s) thereof is not greater than 4.5. |
