Abstract: The invention provides a catalyst for ammonia synthesis which has a high ammonia synthesis activity even at a low reaction temperature and a low reaction pressure and shows no decrease in the catalytic activity even when the synthesis reaction is repeated. The catalyst for ammonia synthesis comprises a metal supported material containing a transition metal and a support for supporting the transition metal. The support contains a metal hydride represented by XHn and an F ion. In the formula, X represents at least one kind selected from the group consisting of atoms of Group 2 and Group 3 of the periodic table, and lanthanoid atoms; and n represents a number represented by 2≤n≤3.
