The ferroelectric relaxor Pb(Sc_{0.5}Ta_{0.5})O_{3}-superconductor YBa_{2}Cu_{3}O_{7-δ} 50% in weight composite exhibits the onset critical temperature T_{c}=95 K. High pressure studies yield the factor dT_{c}/dp of 1.0 K/GPa, close to the value observed for a pure YBa_{2}Cu_{3}O_{7-δ} compound. The microwave absorption studies show the significant role of the intergrain weak links.
