Abstract

See full text

The present disclosure includes: a magnetic member configured to cause a large Barkhausen effect; a power generation coil disposed so as to be wound around the magnetic member; and soft magnetic members formed at both end portions of the magnetic member so as to be in contact with the magnetic member and so as to press the magnetic member. Consequently, evenness of a magnetic flux density inside the magnetic member is increased, and the large Barkhausen effect is stably caused, whereby a highly stable power generation element is obtained.
