Abstract: An ink jet recording sheet having high ink-absorbing ability is disclosed. A porous structure is formed inside of an ink-permeable layer of a recording sheet according to the invention. The total volume of pores having a radius ranging between 100 nm or more and 10000 nm or less is 0.06 cm3/g or more owing to the porous structure.
