A device that pulls out an optical fiber includes: a bobbin support that supports a bobbin rotatably about a rotation axis; a first pulling out unit that holds a first end of the optical fiber, pulls out a first portion of the optical fiber wound around the bobbin from a side of the first end in a state where the bobbin rotates in a predetermined direction, and returns a part of the first portion to the bobbin in a state where the bobbin rotates in a direction opposite to the predetermined direction; and a second pulling out unit that holds a second end of the optical fiber after the first pulling out unit pulls out the first portion from the side of the first end, and pulls out a second portion of the optical fiber wound around the bobbin from a side of the second end.
