PROBLEM TO BE SOLVED: To provide a padlock which has a locking part composed of a block member and a shackle. SOLUTION: The padlock includes a block member 80, a shackle 87 and an indicator 83 (Fig.18). The block member 80 and the shackle 87 form a locking part 800 while the indicator 83 (Fig.18) is mounted in the block member 80. A window 811 provided on the block member 80 shows a first state 831 and a second state 832 (Fig.21) of the indicator 83 (Fig.18). Only after the shackle 87 can open the locking part 800 by means of the block member 87, the indicator 83 (Fig.18) shifts from the first state to the second state (Fig.21), and the state is shown through the window 811, whereas only after the shackle 87 itself can open the locking part 800, the indicator 83 (Fig.18) is reset to the first state 831 from the second state 832 (Fig.21), which is shown through the window 811.
