Pressure‐induced superconductivity is oberserved in Ca10(Pt3As8)(Fe2As2)5 by in situ high‐pressure resistance and magnetic susceptibility measurements. Scaling of the pressure‐induced and doping‐induced superconductivity shows that the electronic phase diagrams of the pressurized and chemically doped 10–3–8 compound are similar in the moderate pressure and doping range but are disparate at higher pressure and heavy doping.
