PROBLEM TO BE SOLVED: To provide a conductive paste that enables the formation of a concave board to be highly precise and accurate electrode lines even by intaglio printing. SOLUTION: A conductive paste for intaglio printing is composed of a conductive powder, glass frit, and an organic vehicle. The conductive powder comprises almost spherical particles having a coagulation rate of not more than 6.0%, tap density of not less than 3.0 g/cm3, average particle size (D50) of 0.3-3.0μm, and specific surface of 0.3-2.5 m2/g.
