The present invention provides a method for producing a silyl enol ether compound, which is convenient, has highly broad utility and places a low environmental load (less waste). The present invention relates to a method for producing silyl enol ether compound (3), including reacting ketone or aldehyde compound (1) with allylsilane compound (2) in the presence of a base and 0.00001 to 0.5 equivalents of an acid catalyst relative to ketone or aldehyde compound (1), wherein R1 is a hydrogen atom, an alkyl group, an aryl group or the like; R2 and R3 are each a hydrogen atom, a halogen atom, an alkyl group, an aryl group or the like; R1 and R3, R1 and R2, or R2 and R3 optionally form a ring, together with the carbon atom(s) bonded thereto; R4 , R5 and R6 are each a hydrogen atom, an alkyl group or the like; two of R4, R5 and R6 optionally form a ring; R7, R8, R9, R10 and R11 are each a hydrogen atom, an alkyl group or the like; two of R7, R8, R9, R10 and R11 optionally form a ring.
