FIELD: physics.
SUBSTANCE: invention is related to electrolytic capacitor that contains layer of metal capable of oxidation, layer of this metal oxide, hard electrolyte and contacts, besides, hard electrolyte used is represented by polythiophens with repeated structural units of common formula (I): 
. Electroconductive layer is also described with specific electroconductivity of at least 150 Cm/cm, which used, for instance, as antistatic coat, transparent heating element, hard electrolyte of electrolytic capacitors, and also for metallisation of through openings of printed circuit boards, etc. This Electroconductive layer is produced due to the fact that mixture of compounds of common formula (II): 
oxidising agent together or separately as solution in dissolvent is applied on substrate, and chemical polymerisation is realised on this substrate at temperature from -10°C to 250°C, producing polythiophens with repeated structural units of common formula (I). Polythiophens used in stated invention have high quality and high electroconductivity, which helps to improve uniformity of coats applied on anode body, which shows in reduction of burrs and number of repeating holes, therefore, higher electroconductivity of such coats is provided.
EFFECT: stated electrolytic capacitor, containing hard electrolyte out of these polythiophens, is characterised by reduced value of serial resistance and lower value of residual current.
