Abstract
A chip inductor is made up of a coiled conducting wire and a magnetic member which is formed by sintering and in which the coiled conducting wire is embedded. Both end portions of the coiled conducting wire are exposed to both end surfaces of the magnetic member. External electrodes are formed with conducting thin films and are connected to respective end portions of the coiled conducting wire. An inorganic material is interposed in a clearance between winds of both end portions of the conducting wire and external surfaces of the magnetic member and a clearance between adjoining winds of the conducting wire.
