Keys in the center columns are made round and those in both outer columns are made square. On the keys in the center column, one-four projections 16 are formed in order from the uppermost key. Then, rows differ in height. At the lower part of the front surface, send key 12 is provided and at the upper part, end key 11 is also provided. On the flank, clear key 13 longer than each key column is provided over the overall length. Along both edges of the front surface, grooves 10a which guide the thumb or the fifth finger of the operator or fixes and holds the position in dialing is formed.
