PURPOSE:To obtain at low cost the titled polymerized film outstanding in insolubility to solvent, electrical conductivity and porosity, by generating a low- temperature gas plasma under a vapor of both pyrrole and iodine to form an iodine-contg. pyrrole plasma polymerized film on a base plate followed by elimination of excess iodine. CONSTITUTION:A low-temperature gas plasma is generated in pyrrole/iodine complex vapor (pref. with a molar ratio pyrrole/iodine=1:20-5:1), pref. in combination with an inert gas to form an iodine-contg. pyrrole plasma polymerized film on a base plate followed by elimination of excess iodine (pref. by rinsing), thus obtaining the objective polymerized film with an iodine content pref. 20-60wt% (pref. having an electrical conductance in the film surface direction 1X10<-3>-1X10<-2>S/cm representing 10<4>-10<7> times that in the film thickness direction, furthermore, giving photoswitching function variable with light irradiation). USE:Photoelectric transfer devices, solar cells, sensors, etc.
