a ladder resistor that includes first to k-th (k is an integer of 2 or greater) resistors connected in series and that outputs a plurality of voltages obtained by dividing a voltage between a first potential and a second potential differing from the first potential by receiving the first potential at one end of the first resistor directly connected to a first node and the second potential at one end of the k-th resistor directly connected to a second node;

a first correction resistor having one end directly connected to the first node;

a second correction resistor having one end directly connected to the second node and another end directly connected to another end of the first correction resistor; and

an amplifier that receives, at an input terminal thereof, a potential of a connection point between the first correction resistor and the second correction resistor, and that has an output terminal thereof connected to a connection point between an r-th (r is an integer of at least 2 but less than k) resistor and an (r+1)-th resistor among the first to k-th resistors;

wherein the first correction resistor and the second correction resistor respectively have resistance values set such that a ratio of the resistance values equals a ratio of a series total resistance value of the first to r-th resistors to a series total resistance value of the (r+1)-th to k-th resistors, among the first to k-th resistors; and

wherein the r-th resistor and the (r+1)-th resistor are connected to a same node.
