COLLECTOR, ELECTRODE STRUCTURE, NONAQUEOUS ELECTROLYTE CELL, AND ELECTRICITY STORAGE COMPONENT

摘要

Provided is a collector having a PTC layer having leeway for thermal expansion during an increase in temperature while ensuring sufficient electroconductivity at regular temperatures. According to the present invention, there is provided a collector comprising an electroconductive substrate and a resin layer provided to at least one surface of the electroconductive substrate. The resin layer includes an organic resin and electroconductive particles. The amount of resin layer adhering on the electroconductive substrate is 0.5 to 20 g/m2. The Rz (ten-point average roughness) of the surface of the resin layer is 0.4 to 10 mum. The Sm (average interval between concavities and convexities) of the surface of the resin layer is 5 to 200 mum. The average of the resistance of the resin layer, measured by the two-terminal method, is 0.5 to 50 Omega.
