PROBLEM TO BE SOLVED: To provide a method for producing a hydrocarbon, by which a Fischer-Tropsch reaction exhibiting a stable catalytic activity for a long time, having high chain growth probability and having excellent lower hydrocarbon olefin selectivity can stably and smoothly be carried out for a long time. SOLUTION: This method for producing the hydrocarbon comprises preliminarily applying a reducing treatment to a catalyst, dispersing a prescribed amount of the reduced catalyst in a liquid hydrocarbon and then bringing the catalyst into contact with a mixed gas consisting mainly of hydrogen and carbon monoxide at a prescribed pressure and at a prescribed reaction temperature. The catalyst is prepared by treating a catalyst precursor prepared by carrying prescribed amounts of a sodium compound and ruthenium on a carrier comprising aluminum oxide and a manganese oxide in which the average charge number of manganese exceeds Mn<SP>2+</SP>, with an alkaline aqueous solution, and has a specific surface area and a bulk density in prescribed ranges, respectively.
