NOVELTY - An electroconductive polymer composition is obtained by curing electroconductive high-molecular compound (I), methylolated phenolic compound (II) and polyhydric phenol compound.    USE - Electroconductive polymer composition is used for forming conductive layer used as electroconductive film for conductor (all claimed). Uses include but are not limited to flexible electroluminescent device, liquid crystal display, transparent touchscreen, organic thin-film transistor, actuator, sensor, electronic paper, flexible light-control material and solar cell.    ADVANTAGE - The conductor provided with the conductive layer obtained using the electroconductive polymer composition is economical and has high electroconductivity, hardness and flexibility.    DETAILED DESCRIPTION - An electroconductive polymer composition is obtained by curing electroconductive high-molecular compound of formula (I), methylolated phenolic compound of formula (II) and polyhydric phenol compound.
