The telephone receiver of this cellular telephone has an earphone type of conical projection suitable to be inserted into an earhole. The conical projection protrudes from the center of a circular base slightly protruding from the upper portion of the body's front surface so that the base comes into close contact with an ear rim when the conical projection is inserted into the earhole. The telephone transmitter of this cellular telephone is slidably received in a lower portion of a telephone body so as to manually or automatically retract into or project out of the body.
