A printing pad 2 has a double-layer structure formed of an elastic body 2a having a substantially quadrangular pyramidal shape, and a coating layer 2d covering a predetermined area of side faces 2b of the elastic body 2a, which predetermined area contains an apex 2c of the elastic body 2a. The elastic body 2a and the coating layer 2d contain silicone oil in order to ensure transfer (pick-up and deliver) of ink and to impart elasticity (flexibility) thereto. The coating layer 2d is harder (contains a smaller amount of silicone oil) than the elastic body 2a. |
