A catalyst for synthesizing acrylonitrile that enables acrylonitrile to be synthesized at high yield, and a process for producing acrylonitrile using that catalyst, are provided. A catalyst for synthesizing acrylonitrile is used having a composition represented by FeaSbbCcDdTeeFfXxYyZzOg(SiO2)h. In the formula, component C represents at least one element selected from the group consisting of Cu, Ni and Co, component D from the group consisting of Mo, W and V, component F from the group consisting of P and B, component X from the group consisting of Sn, Ti, Zr, Nb, Ta, Cr, Ru, Pd, Ag, Al, Ga, In, Tl, Ge, As, Bi, La, Ce, Pr, Nd and Sm, component Y from the group consisting of Mg, Ca, Sr, Ba, Mn, Zn and Pb, and component Z from the group consisting of Li, Na, K, Rb and Cs, and SiO2 represents silica, when a=10, b=5 to 60, c=0.1 to 8.0, d=0.1 to 4.0, e=0.1 to 5.0, f=1.3 to 5.0, x=0 to 5, y=0 to 5, z=0 to 2, h=10 to 200 and g is the atomic ratio of oxygen required to satisfy the valence of each of the elements excluding silicon, and f/d=1 to 5.
