1. A package for an optical fiber comprising:
a base portion;
a plurality of protruding portions that protrude from a flat surface of the base portion, are arranged along an outer periphery of the base portion, and are configured so that an optical fiber including a connector mounted to at least one end thereof is wound along a part of an outer periphery of each of the protruding portions;
a mounting portion to which the connector of the optical fiber is to be mounted;
a plurality of fall-off preventing portions that are formed integrally with the base portion and capable of restricting a position of the optical fiber to be wound over the plurality of protruding portions; and
a plurality of connecting portions that protrude from the flat surface of the base portion, wherein
the connecting portion includes a convex portion at a front end portion in a direction in which the connecting portion protrudes, and has a concave portion recessed forward from a rear surface at a rear end portion in the direction in which the connecting portion protrudes.
