A magneto generator can reduce the man-hours of processing and an amount of use (i.e., an amount of material) of permanent magnets used per generator. The magneto generator includes a bowl-shaped flywheel that rotates about an axis of rotation, a plurality of permanent magnets that are fixedly secured to an inner peripheral wall surface of the flywheel, a stator core that is arranged at an inner side of the permanent magnets and has a plurality of teeth protruding to a radially outer side, and magneto coils that are formed of conductors wound around the teeth, respectively. Each of the permanent magnets is composed of a plurality of magnet pieces that are formed by dividing a hexahedral magnet main body with a division surface extending in a radial direction.
