A scanning endoscope comprising a first transmitter, an actuator, a first mirror, and a second mirror, is provided. The first transmitter emits a beam of radiant light from an emission end. The actuator moves the emission end along a spiral course. The first mirror is arranged from the emission end toward a first direction. The first mirror comprises a first reflection surface around the first direction. The first reflection surface reflects the radiant light emitted from the first transmitter. The second mirror is arranged around the first reflection surface. The second mirror comprises a second reflection surface. The second reflection surface reflects the radiant light reflected by the first mirror in a direction that includes the first direction as a positive vector toward any points on the first line.
