PURPOSE:To provide an electrically conductive paste having excellent mechanical strength and solvent resistance, and removable easily with a solvent, by using a poly-p-hydroxystyrene resin, an epoxy resin and an electrically conductive powder as essential components. CONSTITUTION:The objective composition can be prepared by mixing (A) 100 pts.(wt.) of a poly-p-hydroxystyrene resin of formula (n is 25-95) with (B) 1-80pts., preferably 5-50pts. of an epoxy resin, and (C) an electrically conductive powder having an average particle diameter of preferably <=30mum (e.g. silver powder, copper powder, nickel powder, etc.). The weight ratio of (A+B)/C is 30/70-10/90. |
