ABSTRACT:
A wiring body, used for manufacturing a substrate, includes a columnar body, having an axis, made of fired porous inorganic insulator impregnated with an organic insulator; and a large number of metallic fine wires embedded in the columnar body in parallel with the axis while the metallic fine wires are arranged at intervals, wherein a ratio of the inorganic insulator in the columnar body is 50 to 80 volume %, preferably 50 to 60 volume %. A method for manufacturing a wiring body includes the steps of charging a dispersed solution, in which inorganic insulating powder is dispersed, into a container in which a number of metallic fine wires are arranged in parallel with the axis, drying the dispersed solution, and firing inorganic insulating powder so that the porosity of the fired body can be in a range from 20 to 50 volume % so as to form a columnar body; and the steps of impregnating the obtained porous columnar body with uncured organic insulating material, and curing the organic insulating material.
