[Problem] to provide an array light source capable of being more compact and of conserving space. [Solution] An array light source having: a first array light source (30) including a plurality of semiconductor laser elements arranged in row and column directions and outputting light from each semiconductor laser element; a second array light source (40) arranged facing the first array light source (30), including a plurality of semiconductor laser elements arranged in the row and column directions, and outputting light from each semiconductor laser element; and an array mirror (100) arranged between the first and second array light sources and reflecting laser light from the first and second array light sources, in the X direction. The array mirror (100) has a plurality of slanted surfaces (120) on one side surface (112) and a plurality of array mirrors (100) are laminated such that the one side surfaces (112) thereof are alternately inverted. |
