Superconducting Y-Ba-Cu-O thick films with preferred c-axis orientation were obtained by a screen-printing method. Thick films with preferred c-axis orientation appeared only when the substrate material was YSZ, the film thickness was around 10 μm, and the film was fired at 980 °C for 6 min. The preferred c-axis orientation was caused by an interface reaction between the Y-Ba-Cu-O thick film and the YSZ substrate. The superconducting characteristics of the thick film were T zeroc =89 K and Jc (77 K)=7 A/cm2 .
