PROBLEM TO BE SOLVED: To provide a conductive paste for forming a thick film not generating defective printing by removing lump-shaped impurities with a simple process without accompanying any alteration of the composition of the conductive paste and rheology thereof, and to provide a manufacturing method of the same. SOLUTION: The conductive paste is manufactured by filtrating the conductive paste containing metal powder and an organic vehicle as main components by a filter with a sieve opening of not less than 30μm and not more than 50μm. A viscosity of the conductive paste of 400 Pa s or higher is lowered to 400 Pa s or less by applying a shearing stress on the conductive paste by utilizing a thixotropic property thereof, and the paste is filtrated. Further, an electronic circuit, having a substrate on which the conductive paste is printed, is provided. COPYRIGHT: (C)2006,JPO&NCIPI
