To accurately detect a visual line direction in a wide-angle manner even when a detection range of a visual line direction of a driver has a wide angle relative to a vehicle width direction.SOLUTION: A driver state detection device includes at least two visual line detection parts 12 including a first visual line detection part 21 and a second visual line detection part 22 for detecting a visual line direction 202 of a driver 200, where the first visual line detection part 21 and the second visual line detection part 22 are arranged in positions between which the driver 200 is held relative to a vehicle width direction Y.SELECTED DRAWING: Figure 1
【課題】運転者の視線方向の検出範囲が車幅方向に関して広角であっても、視線方向を広角に且つ高精度に検出する。【解決手段】、運転者200の視線方向202を検出するための第1視線検出部21及び第2視線検出部22を含む少なくとも2つの視線検出部12を備え、第1視線検出部21と第2視線検出部22とは車幅方向Yに関して運転者200を挟む位置に配置されている、運転者状態検出装置。【選択図】図1
