Abstract

Provided are a power generation element, an encoder, a method of manufacturing a magnetic member, and a signal acquisition method capable of reducing variations in generated power. Power generation element includes: magnetic member that produces a large Barkhausen effect by a change in an external magnetic field; and coil wound around magnetic member. Magnetic member includes first magnetic sensing part and second magnetic sensing part having softer magnetism than first magnetic sensing part. First magnetic sensing part is magnetized in a winding axis direction of coil, and a magnetization direction does not change due to a change in a direction of the external magnetic field.
