  We report herein a high and isotropic critical-current density Jc for
BaFe2(As,P)2 epitaxial films. The isotropy of Jc with respect to the
magnetic-field direction was improved significantly by decreasing the film
growth rate to 2.2 {\AA}/s. The low growth rate served to preferentially align
dislocations along the c-axis, which work well as c-axis vortex-pinning
centers. Because of the intentional introduction of effective pinning, the
absolute Jc at 9 T was larger than that obtained for other iron-based
superconductors and conventional alloy superconducting wires.
