An information processing apparatus includes a main case body having installed thereon a key group at a key installation region thereof, a track ball and a selection switch (including a right switch and a left switch) are separately provided, respectively, at a right side region and a left side region of an operator side of the key installation region. The track ball, the right switch and the left switch are provided in such a manner so as an installation region of a wiring substrate. The track ball, the right switch, and the left switch can be easily operated under a key operation feeling by using both hands in a manner similar to operation of the key group. By the foregoing configuration, an increase in an occupied area of a keyboard can be reduced, and increase in a thickness of the keyboard can be restrained, thereby allowing the information processing apparatus to have superior operation characteristics, insofar as its pointing device is concerned.
