Abstract
To provide a resistance device which has a small temperature dependence, in which a resistance value is adjustable in a wide range of from a high resistance value to a low resistance value, and which has a small circuit area, and to provide a current detection circuit including the resistance device. The resistance device is to be connected between two terminals, and a resistance value thereof is variable, the resistance device including: a reference resistor; a series variable resistor circuitry including at least one parallel variable resistor circuit which is connected in series to each other, and which each includes a resistor and a trimming element connected in parallel to the resistor; and a parallel variable resistor circuitry including at least one series variable resistor circuit which is connected in parallel to each other, and which each includes a resistor and a trimming element connected in series to the resistor.
