A current load driving circuit for driving a current load, including: a first current mirror circuit that outputs a current; and a second current mirror circuit that receives the current outputted from the first current mirror circuit as an input current and then amplifies the input current to drive the current load. The whole of the first current mirror circuit and the second current mirror circuit is divided into an input circuit and an output circuit; and the divided position is provided on a voltage route of the first current mirror circuit or a voltage route of the second current mirror circuit.
