PROBLEM TO BE SOLVED: To provide a conductive paste, having very stable printing property, used for screen printing used for forming a circuit pattern to the ceramic circuit board etc., and wherein troubles, such as huskiness, clogging and deterioration of releasability at screen printing, can be suppressed. SOLUTION: In this conductive paste, conductive particles 10, glass particles 12, a disperser 16, 0.8-1.3 wt% of ethyl cellulose, 0.5-1.0 wt% of polypropylene glycol, 0.15-0.25 wt% n-butyl phthalate based on the total weight of the conductive paste, and the remaining of an organic vehicle 14 containing terpineol are mixed and kneaded. Its viscosity characteristics can be nearly approximated by the viscosity formula:η=μD<SP>n-1</SP>(η: viscosity, D: shear rate,μ: non-Newtonian coefficient, n: non-Newtonian index, 0<n<1), at a shear rate sets in the range of 100 sec<SP>-1</SP>to 850 sec<SP>-1</SP>.
