A coin feeding device (for example, feeding unit 20) includes: a disk 22 having a plurality of protrusions 22b at a surface, the disk 22 disposed so as to be rotatable in a tilted state and configured to catch coins by the protrusions 22b to move the coins upward while rotating; a cover 21 configured to form a space for storing a coin between the cover 21 and the surface of the disk 22; a guide 26 configured to guide a peripheral edge of a coin such that a part of the coin having been caught by each protrusion 22b and moved upward protrudes from the disk 22; and a taking-out unit (for example, taking-out mechanism 28) configured to grip only one coin protruding from the disk 22, remove the coin from the disk 22, and discharge the coin to outside of the disk 22.
