Abstract: A light-emitting device includes a laser element array having a quadrangular planar shape, a pair of capacitors that supply an electric current for light emission of the laser element array, and a driving unit that drives the laser element array by turning on and off the electric current for light emission of the laser element array. The pair of capacitors are disposed beside two sides of the laser element array that face each other so as to sandwich the laser element array, and the driving unit is disposed beside another side of the laser element array.
