abstractTo provide: a functional element having, as a structure for obtaining a flexible thermoelectric device having adequate thickness for obtaining a temperature difference, a woven structure in which a yarn composed of a thermoelectric material is woven into a flexible insulating base material having low thermal conductivity; and a method for manufacturing said functional element. [Solution] A functional element in which a spun yarn comprising an electroconductive fibrous substance is woven into an insulating base material that assumes the form of a sheet or band, wherein the spun yarn is composed of an electroconductive fibrous substance, and is woven in so as to pass alternately through the front and rear surfaces of the insulating base material to form a cell series structure of π-type thermoelectric conversion elements. In the electroconductive fibrous substance, p-type characteristics and n-type characteristics are repeated in an alternating fashion in the longitudinal direction, such that the p-type and n-type switch when the spun yarn is alternatingly woven into the front and rear surfaces of the insulating base material and doubled back in the thickness direction of the base material.
