An optical scanning endoscope with an optical fiber, and a fiber driving unit with a plurality of actuators which bend side surfaces of the optical fiber by applying a pressing force. A mounting member is a substantially cylindrical molded interconnect device (MID) component which supports the fiber driving unit. A control circuit supplies driving signals to each of the actuators to control the bending amount and direction of the optical fiber. A wiring member electrically connects wiring patterns on the mounting member with the control circuit. The mounting member has a planar surface section at one proximal-end-surface side of the cylindrical outer-peripheral surface. The wiring patterns include at least first patterns having one end portion disposed on the planar surface section to form soldering lands. The other end portions are electrically connected to the actuators on the proximal-end surface of the mounting member. The wiring member is connected to the soldering lands.
