Zusammenfassung:	PURPOSE:To directly know the hardness easily in case of a fine powder by press-attaching the powder on the standard body surface whose hardness distribution is already known and judging the generation of the scars on the standard body surface and determining the hardness. CONSTITUTION:A measured body 3 is press-contact-slided through the pressing by a necessary force F on the surface of a standard body 4 whose hardness distribution is known already. Then, a scar 5 is generated at the surface part having a low hardness, and when the generation of scars 5 is judged, the powder hardness of the measured body 3 is determined from the hardness of the standard body 4 on the boundary surface of the generation part of the scars 5, and the hardness can be directly known easily even in case of the fine powder.
