Abstract
A fusion splicing apparatus includes a fusion splicing unit, a clock unit that outputs a current date and time, and a fusion control unit that controls an operation of the fusion splicing unit and stops the operation of the fusion splicing unit when a remaining period of use known on the basis of the current date and time output from the clock unit and a usable period input from the outside in advance is zero or less. The fusion control unit records information on the number of times of electric discharge per unit period when the clock unit is normal and determines the remaining period of use assuming that the unit period has elapsed when the number of times of electric discharge has reached the number of times of electric discharge per unit period in a case in which an abnormality of the clock unit is detected.
