There is provided a process for producing a fluorinated vinyl ether from a fluorinated acid fluoride compound having an ester group as a precursor of a carboxylic acid group, or a SO
2
F group as a precursor of a sulfonic acid group, in high yield by simple operations.
Said process is a production process comprising pyrolyzing a carboxylic acid potassium salt with a specific structure represented by the following formula in the absence of a solvent and/or while maintaining the salt in the solid state:
1
wherein X is —CO
2
R or —SO
2
F, and R is an alkyl group.
