By adding a viable lactic acid bacterium to a fat or oil composition, the present invention has succeeded in producing a lactic acid bacterium-containing fat or oil composition that has a high viability of the lactic acid bacterium and an excellent resistance to acids. By adding lactic acid bacteria powder or a chocolate with a high lactic acid bacterium concentration to a chocolate dough after tempering and before molding, moreover, the present invention has succeeded in producing a lactic acid bacterium-containing chocolate including a viable lactic acid bacterium by a simple producing method. Thus, provided is a lactic acid bacterium-containing chocolate with high palatability that contains a viable lactic acid bacterium.
