PROBLEM TO BE SOLVED: To obtain a voltage division circuit allowing reduction in the number of regulation resistance and fuses, without changing combined resistance value after trimming, a constant voltage circuit using the voltage division circuit, a voltage detection circuit using the voltage division circuit, and a trimming method of the voltage division circuit. SOLUTION: Adjusting resistors Ra1 to Ran and adjusting resistors Rb1 to Rbn are weighted by a binary code, respectively, and trimming is performed to each fuse Fb1 to Fbn of a second resistance circuit 3, respectively so that data of binary code showing cutting off state of each fuse Fb1 to Fbn of the second resistance circuit 3 becomes a complement of "1" with respect to the data of binary code showing cutting off state of each fuse Fa1 to Fan of a first resistance circuit 2.
