The present invention provides a device for measuring a hard granular object having a measuring vessel, a holder and a shutter which cannot be damaged by a granule caught between them when used to measure a granular object with high hardness and a method for measuring a hard granular object therewith. The present invention also provides a device and a method for removing fine granules from a hard granular object such as spherical adsorptive carbon containing fine granules and measuring the hard granular object. A device 20 for measuring a hard granular object comprises: a measuring vessel 21 having a first face 21d, a second face 21e parallel to the first face 21d, and a space 21a formed between the first face 21d and the second face 21e for receiving a hard granular object supplied from the first face 21d side; a holder 22 located on the side of the first face 21d, having a through hole 22a communicable with the space 21a, and slidable along the first face 21d; a shutter 24 located on the side of the second face 21e, having a through hole 24a communicable with the space 21a, and movable parallel to the second face 21e; and a pressing means 23 for pressing the holder 22 toward the measuring vessel 21.
