ABSTRACT:
A method of production of peeling layer paste used for producing a multilayer electronic device, having a step of preparing a primary slurry containing a ceramic powder having an average particle size of 0.1 pm or less, a binder, and a dispersion agent and having a nonvolatile concentration of 30 wt % or more, a step of adding to the primary slurry a binder-lacquer solution to dilute the primary slurry to prepare a secondary slurry having a nonvolatile concentration of 15 wt % or less and a content of the binder of 12 parts by weight or more with respect to 100 parts by weight of the ceramic powder, and a high pressure dispersion treatment step of running the secondary slurry through a wet jet mill to apply to the secondary slurry a shear rate of 1.5×106to 1.3×107(1/s).
