Zusammenfassung:To provide a flame-retardant conductive paste that forms a dry coated film which has such excellent flame retardancy that does not catch a fire even when fire occurs in the vicinity or extinguishes fire immediately after the fire occurs, is excellent in conductivity, has adhesion to a base material and is hardly peeled, and can be suitably used as an electrode of a capacitor.SOLUTION: The flame-retardant conductive paste contains flaky silver particles, a resin, a flame retardant and an organic solvent, in which a solid content composed of the flaky silver particles, the resin and the flame retardant is 40-90 wt.%, a content of the flaky silver particles in the solid content is 80-95 wt.%, a weight ratio of the flame retardant to the resin is 91:9 to 40:60, and the flame retardant is a phosphate compound.SELECTED DRAWING: Figure 1 【課題】近辺で出火があったとしても、引火しないか、仮令、引火したとしても直後に鎮火するという優れた難燃性を備えると共に、導電性に優れ、しかも、基材との密着性が高くて剥離し難い乾燥塗膜を形成し、コンデンサの電極に好適に使用できる難燃性導電性ペーストを提供する。【解決手段】フレーク状銀粒子と樹脂と難燃剤と有機溶剤を含有する難燃性導電性ペーストであって、前記フレーク状銀粒子と前記樹脂と前記難燃剤からなる固形分が40〜90重量%であり、前記固形分における前記フレーク状銀粒子の含有量が80〜95重量%であり、前記樹脂対前記難燃剤の重量比が91:9〜40:60であり、前記難燃剤がリン酸エステル化合物である難燃性導電性ペースト。【選択図】図1
