Abstract
An optical fiber photoconductor, comprising at least two multi-filament plastic optical fiber units arranged in parallel and having a substantially rectangular peripheral shape and at least one end fixed in a cap, each optical fiber unit having 50 to 10000 core-sheath light-transmitting islands having a diameter of 5 to 200.mu., which are densely arranged in a sea portion, wherein in each of the multi-filament plastic optical fiber units having a rectangular sectional shape, the end face fixed in the cap is expanded so that the length of one side of the end face is at least 1.01 times the original length of one side of the rectangular peripheral shape of the multi-filament plastic optical fiber unit, whereby a bonding interface between the multi-filament plastic optical fiber units substantially disappears.
