The Y-Ba-Cu-O film prepared by chemical vapor deposition showed T _c=91.5 K and B_c2 (77.3 K)=60 T defined by zero resistance. The J_c values measured at 77.3 K were 7.8×10⁵ A/cm² at B=0 and 1.0×10⁵ A/cm² at 16 T, magnetic fields perpendicular to the c axis. Small disk-shaped precipitates possibly regarded as strong flux pinning centers in the Y-Ba-Cu-O films were observed using transmission electron microscopy. The evaluation of J_c related to the concentration and configuration of the precipitates was in reasonable agreement with the measured J_c values.
