PROBLEM TO BE SOLVED: To provide a projection device capable of easily adjusting the dimension of a projection image. SOLUTION: The projection device 10 with a projection lens 19 for enlarging and projecting modulated light modulated based on an image signal to a projection surface includes a light reflection member 21 provided to move in the optical axis direction of the projection lens 19 and disposed at a position where it is opposed to the projection surface while holding the projection lens 19 in between. The modulated light emitted from the projection lens 19 is reflected by the light reflection member 21 and projected to the projection surface. By adjusting a distance between the light reflection member 21 and the projection lens 19, the dimension of the projection image to be projected to the projection surface is adjusted.
