Abstract
An electric shaver is provided which can enhance the vibration sound by increasing the length of arch-like edges formed between adjacent slots of the inner blade. In the electric shaver, an inner blade having the arch-like edges is moved reciprocally while its outer face contacts with and slides over an inner face of an outer blade to cut beard. The inner blade has an arch-like plate member, as a main body of the inner blade, and it has slots extending from a side wall through a top curved portion to the other side wall, to form arch-like edges between adjacent slots, and the inner blade is connected through a joint to a driver of the main body to be moved reciprocally. Mounting members for the joint are provided at two ends of the inner blade in the longitudinal direction, and the lower ends of the edges at the central portion of the inner blade are set lower than the lower ends of the beads formed above the mounting members of the inner blade.
