PROBLEM TO BE SOLVED: To prevent the problem that the magnetization detecting sensitivity of a conventional magnetic impedance effect element is deteriorated due to the mixing of a magnetic domain whose magnetizing direction is an element longitudinal direction and a magnetic domain whose magnetizing direction is an element width direction in a soft magnetic thin film constituting a magneto-sensitive part. SOLUTION: A magneto-sensitive part 25 is formed by successively laminating a soft magnetic thin film 22, a non-magnetic layer 23, and a soft magnetic thin film 24 so that only a magnetic domain whose magnetizing direction is an element width direction is formed in the soft magnetic thin film 22 and the soft magnetic thin film 24. Thus, it is possible to improve the magnetization detecting sensitivity of the magnetic impedance effect element.
