    Abstract: A drive device for a light-emitting element that improves accuracy while driving the light-emitting element at small currents for which a comparatively simple configuration is provided. The drive device includes detecting means, comparing means, a driving voltage source, and offset means. The detecting means detects a voltage corresponding to a current flowing through a first resistor for current detection. The first resistor is coupled to a light-emitting element in series. The comparing means compares a magnitude of the detection voltage of the detecting unit with a comparison voltage. The driving voltage source applies a voltage corresponding to a comparison result by the comparing means to a series circuit of the light-emitting element and the first resistor. The offset means corrects the voltage corresponding to a current flowing through the first resistor by a correction voltage.
