PROBLEM TO BE SOLVED: To provide an electric fusion apparatus which can reduce the rejected amount of electric fusion joints and resin pipes generated by defective fusion due to unstable power supply, than before. SOLUTION: The electric fusion apparatus is provided with a fusion power source part 11, a fusion power measuring means 122, an input means 121, a control part 12, a control power source part 13, and a control power storing means 14, and gets the voltage and the returning time during the time until the voltage of the fusion power returns to the prescribed value measured by the fusion power measuring means 122 when the voltage of fusion power is detected to be lower than a prescribed value necessary for fusion during fusion. The deficient electric energy is calculated by the control part 12 from the measured result, and a fusion power corresponding to this deficient electric energy is additionally supplied from the fusion power source part 11 to a heater.
