A circuit forming method for forming a circuit with a curable resin and a conductive fluid, the method including a setting step of setting errors that occur during a circuit forming work to an automatic release error and a non-release error for each type of error, the automatic release error being to be automatically released, and the non-release error being not to be automatically released, a determination step of determining whether an error has occurred in work when the circuit is formed, and a re-execution step of automatically re-executing work determined that the error has occurred in the determination step, in a case where the error of the work is set to the automatic release error in the setting step.
