PROBLEM TO BE SOLVED: To provide a trimming circuit capable of preventing the generation delay of reference voltage while preventing current consumption from increasing in the trimming circuit. SOLUTION: The trimming circuit is provided with a short-circuit consisting of two short-circuit resistances and two short-circuit on-off switches and connected to a series resistance circuit in parallel, wherein a middle point of the short-circuit is connected to a connection point of the series resistance circuit whose resistance ratio is equal to a resistance ratio of the short-resistances.
