PROBLEM TO BE SOLVED: To provide a penetration seal can meet heavy user requests by setting an ink replenishing interval long, accurately supply ink by bonding an ink cartridge to an ink absorber with a simpler structure, and print always in a suitable condition without being accompanied by any crushing or blurring of impression of a seal. SOLUTION: The penetration seal includes a main case 1, a printing unit 2, and an ink cartridge 3. The printing unit 2 includes a printing case 9 having an ink cartridge loading hole 15, an ink absorber 10, and a rubber printing body 11. The ink cartridge 3 includes a tank body 22, a tank cap 23, and an elastic part 25 elongated/shrunk in an upper and lower direction. Thus, in a state where the ink cartridge 3 is inserted into the loading hole 15, the tank cap 23 is pressed to the ink absorber 10 by the deformation stress of the elastically deformed elastic part 25.
