Beschreibung
Zusammenfassung:	A first resin member (11) including a first contact surface (12) and formed of laser beam-transmissive resin and a second resin member (21) including a second contact surface (22), which contacts the first contact surface (12), and formed of laser beam-absorbing resin are arranged one upon the other. A laser welding apparatus (1) includes a clamping unit (31) abutting the second resin member (21) and applying clamping force to the second resin member (21), a laser emitter (32) emitting laser beam (Lw), a laser controller (33) controlling output of the laser beam (Lw), a displacement sensor (34) measuring displacement of the second contact surface (22) in stacking direction (X1) of the resin members (11, 21), and a control unit (35) controlling the clamping unit (31) to adjust the clamping force corresponding to displacement amount of the second contact surface (22) continuously or intermittently obtained from the displacement sensor (34).
