PROBLEM TO BE SOLVED: To prevent sticking of ink, at low cost, in a stamp of every size. SOLUTION: The stamp has the part of a penetration seal 12, a block 10 to which the penetration seal is fixed and support members which are fitted removably to the opposite ends of the block. The support member has contact support portions 23b which project outside a seal face 12a and shape-changing portions 23c which connect the contact support portions 23b with the main body of the support member and are elastically deformable. In a standby posture, the contact support portions 23b come into contact with a stamping surface M and thereby a gap is formed between the seal face 12a and the stamping surface M. At the time of stamping, the shape-changing portions change the shape by a pressing force in stamping and thereby the seal face 12a is brought into pressure contact with the stamping surface M.
