To provide a triangular wave generation device for stably outputting a triangular wave.

The triangular wave generation device includes: a triangular wave generating circuit 102 including a first current source 30, a second current source 32, a first switch 34, a second switch 36, an operational amplifier 38, and a capacitor 40; and a feedback circuit 104 which decreases an offset of a signal output from the triangular wave generating circuit 102 from a control reference voltage by controlling the triangular wave generating circuit 102 based upon the offset, and includes a low-pass filter 42, a comparator 44, and a bias adjusting circuit 46.
