To provide a VOC removal catalyst that can be easily produced, has excellent VOC removal efficiency, and can efficiently remove VOCs even at low temperature, a production method thereof, and a VOC removal method.SOLUTION: A production method of a VOC removal catalyst includes a step 1 for mixing a raw material containing a metal element M and a gelatinizer to obtain a gelatinous precursor and a step 2 for burning a product material obtained by mixing the gelatinous precursor and an oxidizer containing Mn, to obtain a complex oxide containing Mn and the metal element M. The metal element M is at least one selected from the group consisting of transition metals, rare-earth elements, and noble metal elements.SELECTED DRAWING: None 【課題】製造が容易であり、ＶＯＣ除去効率に優れ、低温であっても効率よくＶＯＣを除去することができるＶＯＣ除去触媒及びその製造方法並びにＶＯＣの除去方法を提供する。【解決手段】本発明は、ＶＯＣ除去触媒の製造方法であって、金属元素Ｍを含む原料と、ゲル化剤とを混合してゲル状前駆体を得る工程１と、前記ゲル状前駆体と、Ｍｎを含む酸化剤とを混合して得られた生成物を焼成して、Ｍｎ及び金属元素Ｍを含む複合酸化物を得る工程２とを備え、前記金属元素Ｍが遷移金属、希土類元素及び貴金属元素からなる群より選ばれる少なくとも１種である。【選択図】なし
