The purpose of the present invention is to provide an absorbent body and absorbent article having high absorption efficiency. The absorbent body (4) contains non-wood pulp, and the settling rate of the non-wood pulp in water is 2-5 seconds. Furthermore, the average fiber diameter of the non-wood pulp is 8-25[mu]m, and the apparent bulk density is 0.04-0.07g/cm3. The amount of 0.9% saline the non-wood pulp can absorb is at least 20 times the mass of the pulp. The absorbent article (1) contains the abovementioned absorbent body (4). The change in thickness of the absorbent body (4) of the absorbent article (1) after absorbing the 0.9% saline is at least 600% relative to the thickness thereof before absorbing the 0.9% saline. Furthermore, when an evaluation of the absorption rate of the absorbent body (4) is carried out three times, once every 10 minutes, by injecting 80mL of the 0.9% saline into the absorbent article over 10 seconds, the absorption rate for each of the three times is 20 seconds or less. The absorption rate is the duration from the injection of the 0.9% saline until absorption is completed.本發明之課題係在於提供吸收效率高的吸收體及吸收性物品。用以解決課題之手段為,本發明之吸收體,係包含非木材紙漿之吸收體(4),非木材紙漿的水之沈降速度係2秒以上5秒以下。又,非木材紙漿的平均纖維徑為8~25μm,視體積密度(apparent bulk density)為0.04~0.07g/cm3,非木材紙漿的0.9%生理食鹽水的吸收量係對該紙漿的質量呈20倍以上。本發明的吸收性物品(1)係包含上述吸收體(4)。又,吸收性物品(1)的吸收體(4)係吸收0.9%生理食鹽水後的厚度對吸收0.9%生理食鹽水前的厚度之厚度變化率為600%以上。且,花費10秒將80mL的0.9%生理食鹽水注入到吸收性物品(1),每10分鐘進行3次吸收性物品(1)的從該0.9%生理食鹽水的注入到吸收結束的時間之吸收速度的評價之情況,該3次評價中,該吸收速度為20秒以下。1‧‧‧吸收性物品2‧‧‧表面材4‧‧‧吸收體
