Disclosed is a method for producing an alpha,beta-unsaturated ether efficiently and stably for a long time. In the method for producing an alpha,beta-unsaturated ether, an acetal is thermally decomposed in the presence of a catalyst containing an apatite represented by any of the following formulae (1)-(4). <?in-line-formulae description="In-line Formulae" end="lead"?>(M)5-y(HZO4)y(ZO4)3-y(X)1-y (1)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>(M)5-y(HPO4)y(PO4)3-y(X)1-y (2)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>(M)5-y+2n(HZO4)y(ZO4)3-y(X)1-y(SiO4)n (3)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>(M)5-y+m(HZO4)y(ZO4)3-y(X)1-y(CO3)m (4)<?in-line-formulae description="In-line Formulae" end="tail"?>
