Abstract:
A vibration wave motor includes a vibrator, a friction member having a sliding surface, a guide member, a flexible substrate, and a fixing member configured to fix the friction member, the guide member, and the flexible substrate. The vibrator and the friction member move relative to each other in a predetermined direction. The fixing member includes a substrate-fixing portion configured to fix the flexible substrate, which includes a joint portion, an extending portion extending along the predetermined direction, a bent portion configured to reverse and turn back the extending portion, and a fixed portion to be fixed to the substrate-fixing portion. The flexible substrate is fixed on a surface of the substrate-fixing portion provided in a direction opposite to a direction in which the vibrator is brought into pressure-contact with the friction member.
