A bank angle detection device for a motorcycle includes a bank angle estimator configured to estimate a moving body bank angle θb and a correcting section configured to estimate a vehicle body bank angle θf. The bank angle estimator estimates the moving body bank angle θb that is a gradient of a moving body axial line A1, on the basis of a balance state where a centrifugal force CF acting on a moving body and a gravitational force GF acting on the moving body during cornering are in balance with each other. The correcting section corrects the moving body bank angle θb on the basis of an inertia force about a longitudinal axis acting on a vehicle body, so as to estimate the vehicle body bank angle θf that is a gradient of a center of gravity G of the vehicle body with respect to a vertical line.
