1. An electroconductive polymer fiber consisting of a non-electroconductive core layer and an electroconductive layer integrally formed on at least a portion of the surface of the non-electroconductive core layer,
wherein, based on the diameter (d) of the electroconductive polymer fiber, a thickness of the electroconductive layer is 0.25 d or more and 0.6 d or less, and the diameter (d) of the electroconductive polymer fiber is 0.3 mm or more and 3 mm or less,
the non-electroconductive core layer is made of a polymer, and
the electroconductive layer comprises the polymer and a dopant that is an electron acceptor dopant, an electron donor dopant, or both,
wherein the electron acceptor dopant is at least one selected from the group consisting of Cl2, Br2, I2, ICl, ICl3, IBr, IF5, PF5, AsF5, SbF5, BF5, BCl3, BBr3, SO3, NbF5, TaF5, MoF5, WF5, RuF5, PtCl4, TiCl4, AgClO4, AgBF4, HPtCl6, HIrCl6, tetracyanoethylene (TCNE), tetracyanoquinodimethane (TCNQ), dimethyldioxirane (DDO), HF, HCl, HNO3, H2SO4, HClO4, FSO3H, O2, XeOF4, XeF4, NOSbCl6, and NOPF6, and the electron donor dopant is at least one selected from the group consisting of Li, Na, and K,
wherein a repeating unit of the polymer contains at least one double bond and does not contain conjugated double bonds.
