To provide an optical fiber winding bobbin stably storing a winding start optical fiber at high workability and eliminating any breaking of the optical fiber even in the periphery of a hole part.

This optical fiber winding bobbin 10 is provided with a winding drum 1 being a winding part of the optical fiber f, fixed disk flanges 3 and 3 vertically provided in the both sides of the winding drum 1, having a bobbin shaft hole 2 in its central axis, and having one or more holes for taking out the optical fiber fa in the winding start side in at least one of the flanges, and a disk optical fiber storage part 6 having a shaft hole 2 communicated with the shaft hole 2 and having a winding part 5 for winding the optical fiber fa in the winding start side.
