PROBLEM TO BE SOLVED: To provide a fusing and connecting method which can fuse and connect a quartz-based optical waveguide element having a multicomponent glass with a high impurity concentration in a clad and an optical fiber without generating air bubbles. SOLUTION: The quartz-based optical waveguide element 6 and the optical fiber 9 are placed in a pressure chamber 4. The air pressure in the pressure chamber 4 is increased so as to become higher than ambient pressure. The quartz-based optical waveguide element 6 and the optical fiber 9 are fused by heating.
