Coating stripping device and method of manufacturing blade body

A coating stripping device for stripping a coating of an optical fiber, comprising:

• a first blade body having a first facing surface;
• a second blade body having a second facing surface that sandwiches the optical fiber in a facing direction together with the first facing surface;
• and
• positioning pins between the first facing surface and the second facing surface in the facing direction, wherein
• a first fiber groove, into which the optical fiber is fitted to strip the coating, extends in an axial direction intersecting the facing direction,
• a first positioning groove, into which one of the positioning pins is fitted, extends in the axial direction and is disposed at a different position from the first fiber groove in an intersecting direction intersecting both the facing direction and the axial direction
• the first fiber groove and the first positioning groove are open to the first facing surface,
• a second fiber groove, into which the optical fiber is fitted to strip the coating, extends in the axial direction coating,
• a second positioning groove, into which one of the positioning pins is fitted, extends in the axial direction,
• the second fiber groove and the second positioning groove are open to the second facing surface, and
• a distance between the first fiber groove and the first positioning groove in the intersecting direction is substantially equal to a distance between the second fiber groove and the second positioning groove in the intersecting direction.
