  "textContent": "An object of the present invention is to provide a hydrogen permeable material having excellent hydrogen permeability. Another object of the present invention is to provide a composite member and a fuel cell including the hydrogen permeable material. The hydrogen permeable material comprises a perovskite type compound represented by the following general formula (1a). In another embodiment, the hydrogen permeable material comprises a hydrogen-containing perovskite type compound, which is the perovskite type compound represented by the general formula (1a) with introduced hydride ion (H). Wherein M is at least one alkaline earth metal selected from the group consisting of Ba, Sr and Ca, x is a numerical value of 0 or more and 0.3 or less, y is a numerical value of more than 0 and 0.75 or less, w is a value at which an average valence of In is +1.0 or more and +2.5 or less, and y≥w.
