  The single crystal of ThCr2Si2-type BaPd2As2 was successfully prepared by a
self-flux method, and the crystal structure was characterized by X-ray
diffraction method with the lattice parameters a = 4.489(2) {\AA} and c =
10.322(3) {\AA}. Bulk superconductivity below a Tc (critical temperature) of
3.85 K was revealed in this compound by the measurements of resistivity,
magnetic susceptibility and specific heat, and this Tc is much higher than
those of other isostructural Pd-based superconductors.
