PROBLEM TO BE SOLVED: To provide a magnetic impedance element capable of further improving performance by suppressing a disorder of magnetic domain construction generated at a tip of thin film magnetic substance, and to provide its manufacturing method. SOLUTION: In a magnetic impedance element 1, a strip of paper-like thin film magnetic substance 3 is formed on a non-magnetic substrate 2. When high frequency current is fed through this thin film magnetic substance 3, the impedance of the thin film magnetic substance 3 is varied depending on an application of external magnetic field. The tip of the thin film magnetic substance 3 has a profile in which a short side is inclined at a designated angle with respect to a direction crossing a long side in a surface of the non-magnetic substrate 2. A direction, in which the tip of the thin film magnetic substance 3 inclines, coincides with a direction of magnetization easy axis of the thin film magnetic substance 3, and this allows to form a uniform magnetic domain construction few in disorder at the tip of the thin film magnetic substance 3.
