The present invention relates to a catalyst for synthesizing electrochemical ammonia, and a method for manufacturing the same. The catalyst of the present invention has ammonia synthesis activity of several times to several tens of times compared to the conventional single metal or metal oxide catalyst, and thereby can manufacture a catalyst-coated electrode and provide an electrochemical ammonia synthesis method in which the production yield and synthesis rate of ammonia are improved. The catalyst includes iron, copper and sulfur. 본 발명은 전기화학적 암모니아 합성용 촉매 및 이의 제조 방법에 관한 것이다. 본 발명의 촉매는, 기존 단일금속 또는 금속산화물 촉매에 비해 수배에서 수십배에 이르는 암모니아 합성 활성을 가지며, 이를 이용하여 촉매가 코팅된 전극을 제조하고 암모니아의 생산 수율 및 합성속도가 향상된 전기화학적 암모니아 합성방법을 제공할 수 있다.
