The present invention is to provide a control apparatus, which includes a casing with two sides each comprising a holding portion extending outwardly and towards a bottom thereof for being held by a user while viewing a front of the casing, the front is inclined progressively from a lateral edge of the front away from the user through the bottom to an opposite lateral edge of the front near the user; a direction input portion disposed on the front of the casing near one of the holding portions; an operation input portion disposed on the front of the casing near the other holding portion; and a sensing input portion disposed on the front of the casing between the direction input portion and the operation input portion and proximate to the user. Thus, a user can press or push any input portion easily for an input while holding the two holding portions by hands.
