PROBLEM TO BE SOLVED: To provide a seal impression capable of clearly impressing. SOLUTION: An elastic member 2 is cross-sectionally provided above the impressing surface 3 of the seal impression, and the impression is separated into an upper part 4 and a lower part 5 through the member 2. The member 2 is preferably provided under a grip 1 or lower than the grip 1. The member is provided so that an impressing pressure to be applied down from the grip is uniformly transmitted to the impressing surface. The member is necessarily substantially uniform in thickness. The thickness of the member is not particularly limited, but when the member is excessively thin, it becomes insufficient to uniformly disperse an impressing force to the impressing surface. When the member is excessively thick, its effect is not improved, but a sense of instability is rather sensed when impressed. The thickness is preferably 0.1 to 30 mm or more preferably 1 to 10 mm. The material of the member is a natural rubber, a synthetic rubber, a soft synthetic resin, a foamed resin or the like is used.Δmong them, the natural and synthetic rubbers are preferred.
