An adsorbent consisting of iron oxyhydroxide, having a high adsorption rate and high adsorption efficiency compared with conventional products. The adsorbent particle is an adsorbent particle having a crystal structure of β-iron oxyhydroxide, having an average crystallite diameter of 10 nm or less as measured by X-ray diffraction, wherein 90% or more of volume of adsorbent particle is constituted of granular crystals having crystal particle diameter of 20 nm or less, or columnar crystals having width of 10 nm or less and length of 30 nm or less. The adsorbent particle have at least either of the following characteristics: (A) the adsorbent particle contains metal element other than iron in amount of 0.1 to 20% by mass with respect to iron element, or (B) the adsorbent particle contains sulfur oxoacid ions in an amount of 0.01 to 20% by mass in terms of sulfur element with respect to iron element.
