A device for measuring undulation of a brake disc in a railway wheel with brake discs includes a wheel support supporting a hub's bore of the railway wheel; a first displacement gauge for measuring a height displacement of the brake disc frictional surface for one round to follow rotation of the wheel support; and a second displacement gauge for measuring a height displacement of a railway wheel rim surface for one round to follow rotation of the wheel support. A computing unit calculates a difference between maximum and minimum values of the height displacement of the frictional surface by acquiring measurement data from the first displacement gauge, calculates a difference between the maximum and minimum values of the height displacement of the rim's surface by acquiring measurement data from the second displacement gauge, and derives a difference between the both calculated differences as brake disc undulation.
