The present invention provides a holding apparatus including a structure and configured to hold an object so that a distance from a reference point of the structure to a reference point of the object in a direction along a reference axis is kept at a constant value, the holding apparatus including a plurality of holding members, each being supported by the structure, including an inclined surface that is inclined relative to a plane orthogonal to the reference axis, and being configured to hold the object via the inclined surface, wherein the inclined surfaces are inclined so that the distance falls within a tolerance even if temperature of the object and the plurality of holding members change.
