It is an object of the present invention to provide a lactic acid bacterial immunopotentiating activity-increasing composition that increases the immunopotentiating activity of lactic acid bacteria having immunopotentiating activity； and a method for increasing the immunopotentiating activity of lactic acid bacteria using the composition； and a composition comprising both of lactic acid bacteria having an immunopotentiating activity and a lactic acid bacterial immunopotentiating activity-increasing composition, wherein the immunopotentiating activity of the lactic acid bacteria is increased. The present invention relates to a composition comprising lactic acid bacteria having an immunopotentiating activity and a lactic acid bacterial immunopotentiating activity-increasing composition comprising an ester compound of a polyol and a saturated fatty acid as an active ingredient.
