PROBLEM TO BE SOLVED: To enable high accuracy, reliable temperature control by holding the top surface of a heat block, holding a body to be bonded consisting of an optical fiber inserted into the through hole of a ferrule through a thermosetting adhesive and the ferrule at nearly uniform temperature without causing any temperature unevenness. SOLUTION: In this device, a heater 4 is housed nearly horizontally to overall length along the length in a heat block part 3 supporting a heated block 2, where hold parts 2a holding ferrules F1 are arranged side by side. A control part 6 controls the heater 4 according to the temperature detected by a temperature sensor 5 provided on the flank of the heat block part 3 nearby the lengthwise center part of the heater 4. |
