NOVELTY - An electroconductive paste comprises rubber, acrylic or silicone-type organic substance binder (A), electroconductive filler (B) and tackifier (C). The paste forms conductive layer (4) between outer layer of collector (5) and metal electrode plate (6) of battery. The battery has battery cell or capacitor element having collector clamped between electrode and gasket by metal electrode plates using conductive layers.    USE - For manufacture of battery or electric double layer capacitor (claimed).    ADVANTAGE - The electroconductive paste has excellent adhesion of collector and metal electrode plate, and prevents corrosion and contamination of electrode by residual solvent and residual monomer component in cured material. The battery or electric double layer capacitor formed using the electroconductive paste has excellent stability and reliability of electrical property.    DETAILED DESCRIPTION - An electroconductive paste comprises a rubber-type, an acrylic-type or silicone-type organic substance binder (A), electroconductive filler (B) and a tackifier (C). The electroconductive paste forms a conductive layer (4) between outer layer of collector (5) and metal electrode plate (6) of a battery. The battery has water or an organic-solvent type electrolyte liquid, a separator (2), a pair of electrode layer (1) separated by separator, a gasket (3) maintained at the periphery portion of electrode layer, and a battery cell or capacitor element having a collector (5) clamped between the electrode layer and gasket by metal electrode plate (6) using two sheets of conductive layers (4).    An INDEPENDENT CLAIM is included for manufacture of battery or electric double layer capacitor, which involves connecting the collector and the metal electrode plate of the battery cell or capacitor element, applying the electroconductive paste on one surface of the metal electrode plate, drying or hardening the paste, and then press-sticking and joining the coated surface with the collector, at normal temperature.    DESCRIPTION OF DRAWING(S) - The figure shows the model drawing of the construction method of battery or electric double layer capacitor using the electroconductive paste.    polarizing electrode (1)    separator (2)    gasket (3)    conductive layer (4)    collector (5)    metal electrode plate (6)
