Outline of Final Research Achievements	The change of the electronic structure of highly-oriented poly(3-hexylthiophene) thin films upon hole doping was investigated by　photoelectron spectroscopy. Highly-oriented thin film samples were prepared by friction transfer method. Band dispersion along the main chain direction was not observed. The energy of the quasiparticle peak in the UPS of doped films changes upon doping, which suggests the change of the type of quasiparticles.
