At this time, since the holder 91 is locked to the key body 12 by the engagement of the projection 93 and the locking groove 12N, the key body 1 2 is pressed by the pressure of the hot water pressed into the mold. There is no misalignment. Further, since the pressure of the hot water acts in a direction to push the transmitting element 21 into the housing 92, the transmitting element 11 does not come out of the housing 92. This resin thermoforming is performed in a state where the key body 12 is horizontal or the base 12 B side is lifted up.

Further, the transmitting element 21 molded with resin has excellent water resistance. For example, it is possible to drop the key 10 into water. Also, since the transmitting element 21 is assembled to the key body 12 via the holder 91, the transmitting element 21 is arranged at a desired position at a predetermined distance (about several mm) from the base 12B.
