Abstract
An optical device according to an embodiment includes a lens mirror array and a holder. The lens mirror array is opposed to a light emitting section. The lens mirror array includes a plurality of optical elements. The optical elements include incident-side lens surfaces, emission-side lens surfaces that emit incident light, and reflection surfaces that reflect incident light. A cross section orthogonal to a first direction of the lens mirror array has a constricted shape. The holder includes a slit having width smaller than width of both the ends in the cross section of the lens mirror array and larger than width of the center in the cross section and extending in the first direction. The holder holds the lens mirror array in a state in which a constricted portion in the center in the cross section of the lens mirror array is disposed in the slit.
