PROBLEM TO BE SOLVED: To enhance the mutual conductance of an active load circuit without increasing the consumption of a load current and without enlarging a chip occupied area. SOLUTION: An active load circuit is composed of a first main current generation circuit 1 which generates a first load current, a first sub-current generation circuit 3 which generates a load current of a predetermined ratio for the value of the first load current, a second main current generation circuit 2 which generates a second load current, and a second sub-current generation circuit 4 which generates a load current of a predetermined ratio for the value of the second load current. An output terminal 12 which outputs the current from the first main current generation circuit 1 and an output terminal 42 which outputs the current of the second sub-current generation circuit 4 are commonly connected, and an output terminal 22 which outputs the current from the second main current generation circuit 2 and an output terminal 32 which outputs the current of the first sub-current generation circuit 3 are commonly connected.
