Abstract

An object of the invention is to provide an adsorbent having high adsorbability per unit volume and a high adsorption rate as an adsorbent for water treatment or medical care and to provide an adsorbent capable of completely adsorbing an aimed substance within a short time as an adsorbent for medical care. The desired adsorbent is an adsorbent produced from a phenol resin as a starting material and having 0.10 to 0.60 ml/g of volume of fine pores with diameters in a range from 0.02 to 10 .mu.m, a specific surface area in a range from 800 to 3000 m.sup.2/g, and an average particle diameter in a range from 0.1 to 0.8 mm. The adsorbent is produced by conducting carbonization of the phenol resin as a starting material at 350 to 550.degree. C., then heating up to 700 to 950.degree. C. at a rate of 5 to 20.degree. C./min, and successively carrying out activation of the obtained carbonized product.
