One object is to provide a method for measuring current by which minute current can be measured. A value of current flowing through an electrical element is not directly measured but is calculated from change in a potential observed in a predetermined period. The method for measuring current includes the steps of: applying a predetermined potential to a first terminal of an electrical element having the first terminal and a second terminal; measuring an amount of change in a potential of a node connected to the second terminal; and calculating, from the amount of change in the potential, a value of current flowing between the first terminal and the second terminal of the electrical element. Thus, the value of minute current can be measured.
