 note = {(Ba,K) Fe2As2 superconducting wires and tapes are fabricated by using hot isostatic pressing (HIP) technique, and their superconducting properties are studied. In the HIP round wire, transport critical current density (J(c)) at 4.2 K has achieved record-high value of 175 kA cm(-2) at zero field, and exceeds 20 kA cm(-2) even at 100 kOe. Improvement of polycrystalline powder synthesis may play a key role for the enhancement of J(c). In the HIP tape, even larger transport Jc of 380 kA cm(-2) is realized at zero field. Based on magnetization and magneto-optical measurements, possible further enhancement of J(c) is discussed.},
