Abstract

An activated carbon fiber is obtained by activating: a polyphenylene ether fiber that contains a polyphenylene ether component having a rearrangement structure connected by a bond at an ortho-position in a repeating unit continuously bonded at a para-position; an infusibilized polyphenylene ether fiber obtained by infusibilizing the polyphenylene ether fiber; a flameproofed polyphenylene ether fiber obtained by flameproofing the polyphenylene ether fiber or the infusibilized polyphenylene ether fiber; or a carbon fiber obtained by carbonizing any of the polyphenylene ether fibers.
