PROBLEM TO BE SOLVED: To provide a stamp easy to be aligned 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: Since a protrusion 33 of a lower main holder 3b is inserted into and engaged with a recess 34 of an ink storage material 12, a positional deviation of the material 12 from the holder 3b can be prevented so that the material 12 and the holder 3b are not positionally deviated to be adhered. Accordingly, since it is not necessary to surround peripheries of the material 11 and the material 13 by a main holder 3 for positioning, excess seal surface margin can be prevented.
