Abstract
A scanning endoscopic device includes an optical fiber allowing irradiation light guided from a proximal side fiber portion to a distal side fiber portion to exit from a distal end thereof, and an actuator section placed to a distal direction side of the proximal fiber portion. The scanning endoscopic device includes a light absorbing section absorbing beam light having directivity in one direction, and the light absorbing section includes a black filling member filling a space between the proximal side fiber portion and an outer envelope tube in radial directions. The device further includes a light scattering section provided between the proximal side fiber portion and the outer envelope tube in the radial directions to scatter the beam of light.
