PURPOSE:To increase an effective magnetic flux which acts on a magnetic reluctance element so as to improve a magnetosensor in conversion efficiency by a method wherein a ferromagnetic thin film is formed on a space adjacent to two or more magnetic reluctance elements formed on an insulating substrate being insulated from other conductive sections. CONSTITUTION:Two or more magnetic reluctance elements 4-1 formed of a magnetic thin film are provided onto an insulating substrate 3-1 at the pitch of pi, and magnetic flux induction sections 5 are provided to an empty space between a terminal section 4-3 of the element 4-1 and a lead-out section 4-2 which servess both as connecting sections and lead-out terminals of two elements and the element 4-1 and the lead-out section 4-2, being insulated from other conductive sections. By these processes, a magnetic flux generated from a permanent magnet is induced to the magnetic induction section 5 and made to enable to the ratio of its portion which passes in parallel through the magnetic reluctance element 4-1 to itself to increase. As a result, the magnetosensor 3 can be improved in conversion efficiency. |
