An electronic device includes a living-body signal receiver that receives a living-body signal, and a display information processor that calculates living-body information based on a living-body signal received by the living-body signal receiver, that measures and outputs internal measurement information, and that determines whether or not the living-body signal receiver receives the living-body signal. A display is configured to display the living-body information and the internal measurement information. A display controller performs a switching operation to switch between the living-body information and the internal measurement information for display on the display based on the result of the determination by the display information processor.
