Abstract
A current source circuit flowing an output current to at least one detection element including a first terminal to which a first voltage is supplied and a second terminal being connected to the current source circuit includes a reference resistance, a current mirror circuit including at least one first transistor and at least one second transistor, and a control circuit controlling a voltage of a common wire that is connected to a terminal provided at the first transistor and a terminal provided at the second transistor such that a voltage of a terminal provided at the reference resistance comes to be equal to a reference voltage.
