Abstract: This application provides a magnetic element, a power supply, and an electronic device. The magnetic element includes a magnetic core, a coil, and a skeleton, an accommodation space is provided in the magnetic core, and the coil is located in the accommodation space. Surfaces of the magnetic core include a first end face, a second end face, and a side surface connecting the first end face and the second end face. The skeleton is disposed on the side surface and is fixedly connected to the magnetic core. The first end face is flush with or protrudes from one end of the skeleton, and the second end face is flush with or protrudes from the other end of the skeleton.
