PROBLEM TO BE SOLVED: To provide a stamp easy to align at stamping by suppressing a sealing surface margin to be generated with respect to contact of a seal surface unit with a holder to a small area. SOLUTION: A press injecting cap of a cylinder made of stainless steel having a thickness of 0.2 mm is press injected from a seal material 11 to an ink storage material 12 to connect the material 11 and the material 12 to a main holder 3. A sealing portion disposed on a peripheral edge of the material 11 is fixed by a pressing potion 44 having a width of 0.5 to 1.0 mm, and a seal surface 1 of the material 11 is projected externally from a first opening 43 about 0.05 to 1.0 mm.
