Abstract: Provided are a power generation element, an encoder, and a method of manufacturing a magnetic member capable of increasing generated power. Power generation element includes magnetic member that produces a large Barkhausen effect, coil wound around magnetic member, and ferrite member provided at an end of magnetic member to be aligned with coil along a winding axis direction of coil. Ferrite member includes main body located inside columnar space and protrusion connected to main body and located outside columnar space. Columnar space is surrounded by a virtual plane when it is assumed that an outer edge of coil when viewed from the winding axis direction of coil is extended to both sides of the coil in the winding axis direction of coil, and is sandwiched between two virtual planes that are in contact with both ends of magnetic member in the winding axis direction of coil and are orthogonal to the winding axis direction.
