Abstract
A fusion splicer includes a first electrode, a second electrode, an optical fiber disposition unit, and a first conductive member. The first electrode has a first potential, the second electrode has a second potential lower than the first potential, and an arc discharge is generated therebetween. The optical fiber disposition unit has grooves in which first optical fibers and second optical fibers are accommodated. The first conductive member is provided apart from the grooves between the first electrode and the second electrode. The first conductive member has a third potential that is lower than the first potential and higher than the second potential, and is disposed at a position at which the shortest distance from one of the first electrode and the second electrode is shorter than the shortest distance from the other of the first electrode and the second electrode.
