    Abstract: PROBLEM TO BE SOLVED: To provide an electroconductive composition capable of attaining high electrical conductivity and high adhesion to a base material.SOLUTION: The electroconductive composition is constituted of an electroconductive metal powder containing metal flakes and an epoxy resin component containing a polyfunctional epoxy resin having three or more epoxy groups (for example, a glycidyl ether-type aromatic epoxy resin or the like). In such a composition, the average particle diameter of the metal flakes may be 0.7-10 μm, the BET specific surface area may be 1-5 m/g, and the tap density may be 0.5-4.5 g/cm, and when the average particle diameter of the metal flakes is defined as A(μm) and the BET specific surface area is defined as B(m/g), the value of A×Bmay satisfy 4-30.
