An enteral nutrient gel that is excellent at maintaining its solid matter (gel) form in the stomach, does not readily disintegrate or dissolve with a change in pH, is stable in its physical properties even during long-term storage, and can be passed through a feeding tube. The enteral nutrient gel contains agar, alginic acid and/or a salt thereof, soybean protein or a hydrolysate thereof, calcium, magnesium, dextrin, and, optionally, an oligosaccharide, a disaccharide and/or a monosaccharide. A solid composition containing 8 to 30 wt % protein, 2 to 25 wt % fats, and 40 to 70 wt % dextrin is used in preparing the enteral nutrient gel.
