1. A fiber cutter comprising:
a base member configured to hold an optical fiber;
a moving member that is movable with respect to the base member in a front-rear direction of the base member, wherein the optical fiber held by the base member extends along the front-rear direction;
a placement surface on which an end part of the optical fiber is placed;
a gripping tool that grips the end part of the optical fiber;
a blade that forms an initial cut in the optical fiber gripped by the gripping tool; and
a support plate that applies a predetermined bending stress to the optical fiber when the blade forms the initial cut in the optical fiber, wherein
the placement surface, the gripping tool, and the support plate are located on the moving member,
the blade is configured to be inserted into a gap between the support plate and the placement surface to form the initial cut in the optical fiber, and
the support plate is attached to the placement surface and stands upright from the placement surface such that a positional relationship between the support plate and the placement surface is constant with respect to an up-down direction perpendicular to the front-rear direction.
