A portable electronic equipment is capable of preventing warpage of an internal substrate accommodated therein due to pressing operations of button keys to thereby improve the mechanical strength thereof and contribute a downsizing thereof. To this end, a stopper14is provided on a front case1for limiting the amount of depression of each button key8. The stopper14has a shape to support an entire outer periphery of a flange15of each button key or a shape to support an outer periphery of a flange15of each button key radially in a plurality of directions. Also, key seats19for the button keys are connected with each other in a bridge-shaped configuration, or formed separately or independently from each other. In addition, the front cover is provided with a case cover for preventing the button keys from popping out therefrom.
