METHOD FOR MEASURING CONDUCTIVE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide conductive paste for stably forming a viahole conductor of high quality reduced in variations and realizing a circuit forming substrate having high connection reliability.

SOLUTION: A method for measuring conductive particles containing primary particles and flocculated particles thereof includes a process for obtaining the average particle size of primary particles, a process for obtaining the average particle size of flocculated particles and a calculation process using the following formula. The conductive particles contained in the conductive paste are measured numerically by this measuring method. The conductive paste having good flowability and dispersibility can be provided by manufacturing the conductive paste on the basis of this measuring method.
