SOLUTION: This keytop structural body is provided with the rubber molded base 15 molded to form a three dimensional shape having a protrusion 14, and a hard resin made keytop 17 disposed on the protrusion 14. The jointing face 16 of the protrusion 14 of the rubber molded base 15 is bonded to the jointing face 18 of the keytop 17 by an adhesive 19, a hollow part 30 is provided on the jointing face 16 of the protrusion 14 of the rubber molded base 15, and the adhesive is made to exist in the hollow part 30. Therefore, the contact area of the adhesive 19 and the rubber molded base 15 is made larger than the contact area of the adhesive 19 and the keytop 17. COPYRIGHT: (C)2005,JPO&NCIPI
