Proposed are a functional microcapsule processed to contain therein a germanium component having various physiologically active characteristics and a functional textile fabric to which the functional microcapsules are applied. The functional microcapsule includes a lipophilic oil, germanium ore powder or germanium oxide powder dispersed in the oil, and a shell made of a polymer material and containing therein the oil in which the germanium ore powder or germanium oxide powder is dispersed. These proposals may solve the problem of poor resistance to washing and poor washing durability, which have been pointed out as problems with conventional use of germanium, and may facilitate attachment and fixing of germanium to various media.
