A brake control device of a brake device includes a first acquisition unit acquiring an operating force PF inputted to a brake pedal, a second acquisition unit acquiring a stroke amount SS of the brake pedal, a target derivation unit deriving a target braking power BPTr based on the operating force PF and the stroke amount SS, and a brake controller controlling a vehicle braking power based on the target braking power BPTr. The target derivation unit increases or holds the target braking power BPTr when the operating force PF decreases while the stroke amount SS increases.
