We report on the observation of a superconducting transition in a fiber-like film of the phase electrodeposited on silicon substrates. Superconductivity is evidenced by a broad drop of the resistance below 0.8 K under the application of a hydrostatic pressure of 7.7 kbar. Zero resistance is not reached due to the contribution of inter-fiber resistance. Superconductivity is confirmed by the application of a magnetic field perpendicular to the plane of the film. The critical field determined on the film is in agreement with that obtained in bulk single crystals.
