  A q-deformation of the ADHMN caloron construction is considered, under which
the anti-selfdual (ASD) conditions of the gauge fields are preserved. It is
shown that the q-dependent Nahm data with certain constraints are crucial to
determine the ASD gauge fields, as in the case of ordinary caloron
construction. As an application of the q-deformed ADHMN construction, we give a
q-deformed caloron of Harrington-Shepard type. Some limits of the parameters
are also considered.
