PROBLEM TO BE SOLVED: To allow measuring hardness of a structure placed underwater. SOLUTION: An inspection apparatus inspects the hardness of the structure partially placed underwater. An impression is formed on the structure 1 by an indenting needle 5. A first piston 7 is attached to the indenting needle. The indenting needle and the first piston are accommodated in an indentation vessel 3. A replica liquid storing vessel 14, having a nozzle 12, is held in the indentation vessel. A second piston 15 is held in the replica liquid storing vessel. The first piston is pressurized by first pressurizing means 9, 10. The second piston is pressurized by a second pressurizing means 18. The indentation vessel is remotely operated by a remote operation means. The remote operation means has a control means for controlling pressure of the first and second pressurizing means. Pressing of the indenting needle to the structure and of spraying a replica liquid from the nozzle are exclusively implemented. COPYRIGHT: (C)2005,JPO&NCIPI
