A traffic cone has an annular base and a hollow conical body. The annular base has an annular panel having multiple through holes, and multiple first feet protruding down from the annular panel. The conical body has a conical portion and a covering panel radially protruding from a bottom peripheral edge of the conical portion and wrapped on the annular panel. Moreover, even if the traffic cone is bumped or is run over by cars, the annular and the conical body do not separate from each other easily so the traffic cone has prolonged life for use.
