摘要： The present invention provides a constant current circuit and a constant current generating method, wherein when a voltage slight in temperature dependence is applied to an element to output a constant current, temperature dependence of the element can be cancelled. A current indicative of first temperature dependence, which is generated by applying a bias voltage slight in temperature dependence to a first current setting section, and a current indicative of second temperature dependence, which is generated by applying a bias voltage slight in temperature dependence to a second current setting section are added and outputted as a constant current slight in temperature dependence. When a bias voltage slight in temperature dependence is applied to a current setting section having resistive components to generate currents, even where the resistive components have temperature dependence, the first and second current setting sections having temperature dependence opposite to each other are parallel-connected and bias voltages are applied thereto, after which the generated currents are added together. Consequently, the temperature dependence contained in the individual current setting sections can be cancelled out and hence a constant current slight in temperature dependence can be outputted.
