PROBLEM TO BE SOLVED: To provide a method for efficiently producing olefin polymers by suppressing sheeting in a gas phase fluidized bed polymerization, and to provide equipment therefor. SOLUTION: The gas phase fluidized bed polymerization reactor used for subjecting olefins to gas phase polymerization in the presence of catalysts has an inner surface in contact with powder particles composed of a fluorocarbon resin, and particularly has a gas-dispersing plate whose surface is composed of a fluorocarbon resin at the bottom of the reactor. The method for producing olefin polymers comprises subjecting olefins to gas phase polymerization in the presence of catalysts by using the gas phase fluidized bed polymerization reactor having an inner surface in contact with powder particles composed of a fluorocarbon resin, and particularly by using the gas phase fluidized bed polymerization reactor having a gas-dispersing plate whose surface is composed of a fluorocarbon resin at the bottom of the reactor.
