Abstract

An inventive multilayer type chip inductor includes a pair of outermost sheets having a terminal pattern, respectively, and a plurality of intermediate sheets stacked between the outermost sheets. Each of the intermediate sheets has one turned coil-shaped conductor pattern in an electric contact with the terminal pattern of the outermost sheet. Each of the conductor patterns is spirally and outwardly turned from a central portion of the intermediate sheet.
