A rotation angle detection device for a vehicle brake includes: a housing accommodating a magnetic detection unit; a rotation member supported to be rotatable relative to the housing; and a magnet held by the rotation member and rotating integrally with the rotation member, in which the magnetic detection unit includes a stroke detection unit and a switch detection unit, the stroke detection unit detects a rotation angle by which the rotation member has rotated from a reference position based on a magnetic force of the magnet, the switch detection unit detects that the rotation member has rotated from the reference position by a predetermined angle or more, and at least a portion of the stroke detection unit is disposed at a position where the portion overlaps with the magnet in an axial direction of a rotational axis of the rotation member.
