Provides a new non-oxide system compound material superconductor as an alternative of the perovskite type copper oxides superconductor. Layered compounds which are represented by chemical formula AF(TM)Pn (wherein, A is at least one selected from a group consisting of the second family elements in the long form periodic table, F is a fluorine ion, TM is at least one selected from a group of transition metal elements consisting of Fe, Ru, Os, Ni, Pd, and Pt, and Pn is at least one selected from a group consisting of the fifteenth family elements in the long form periodic table), having a crystal structure of ZrCuSiAs type (space group P4/nmm) and which become superconductors by doping trivalent cations or divalent anions.
