Abstract

Provided is a magneto-impedance element (an MI element) which can attain an increase in output power and size reduction. In the MI element of the present invention, a detection coil (13) winding around a magneto-sensitive wire (12) provided above a substrate (11) comprises a first wiring part (131) comprising film-shaped electrically conductive bodies formed along a flat surface of the substrate and crossing the magneto-sensitive wire; a second wiring part (132) comprising film-shaped electrically conductive bodies formed on an opposite side of the magneto-sensitive wire to the first wiring part and crossing the magneto-sensitive wire; and a connecting part (133, 134) comprising columnar or tubular electrically conductive bodies surrounded by an electrically insulating part at both lateral sides of the magneto-sensitive wire and extending in a normal direction of the substrate so as to connect predetermined positions of the first wiring part and those of the second wiring part. Upon providing the connecting part, the wiring parts can be formed with a high resolution and the MI element can attain both a fine pitch of a detection coil, that is, an increase in output power and size reduction.
