PROBLEM TO BE SOLVED: To provide a conductive paste composition which can assure sufficient substrate reliability for a moisture absorption reflow thermal resistance, a resistance value, etc. even when a crystalline thermoplastic resin is used for an inner layer, an outer layer and conductor wiring of a via hole in a batch multilayer wiring board using a crystalline thermoplastic resin for an insulation base material in a heat curing type conductive paste composition used for the multilayer wiring board. SOLUTION: The conductive paste composition for the multilayer wiring board is used for the multilayer wiring board obtained by batch laminating the wiring board, containing a conductive paste composition on the front surface of an insulating base material obtained from a crystalline thermoplastic resin composition and in the via hole by heat fusion bonding. The conductive paste composition contains a conductive powder, an inorganic ion exchanger, and a resin mixture containing an epoxy resin and a curing agent. The curing peak temperature of the resin mixture is the glass transition temperature (Tg) minus 15°C of the crystalline thermoplastic resin composition to lower than the crystallization peak temperature (Tc).
