Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a medicine-holding carrier which can immobilize a substance such as a medicine only with a calcium aqueous solution and can further simply control a medicine-releasing rate in dependence to the concentration of calcium, or the like. SOLUTION: The subject additive for gelation is obtained by hydrolyzing pectin with an acid to lower the mol. wt. of the pectin. The subject method for producing the medicine-holding carrier is characterized by adding a medicine to a solution containing the additive for the gelation and pectin, homogeneously stirring the mixture, and then dropping the obtained solution on a calcium aqueous solution to obtain the spherical gel beads.
