Abstract: A probe includes a movable plate to which a stylus capable of contacting a measurable object is mounted, the movable plate displaceable in an X direction; a static plate arranged to overlap with the movable plate; a counter plate facing the movable plate and the static plate; an elastic movable side connection plate, the movable side connection plate connecting the counter plate at at least three places with each of a first end connector positioned toward a first end of the movable plate in the X direction and second end connectors positioned toward a second end in the X direction; and a static side connection plate which connects the static plate and the counter plate. An entire length of the first end connector in a Y direction orthogonal to the X direction is the same size as the entire length of the second end connectors in the Y direction.

Abstract: A surface texture measuring apparatus includes an X axis displacement mechanism and a Y axis displacement mechanism displacing a measurable object having an interior wall along an XY plane; a measurement sensor measuring a surface texture of the interior wall without contact; a Z axis displacement mechanism displacing the measurement sensor in a Z axis direction orthogonal to the XY plane and bringing the measurement sensor to face the interior wall; a W axis displacement mechanism displacing the measurement sensor facing the interior wall in a normal direction of the interior wall; and a θ axis displacement mechanism displacing the measurement sensor facing the interior wall along the interior wall.
