Water absorbent resin particles and absorbent article

Water-absorbing resin particles comprising:

• a crosslinked polymer having a monomer unit derived from an ethylenically unsaturated monomer comprising at least one compound selected from the group consisting of (meth)acrylic acid and a salt thereof,
• wherein a proportion of a (meth)acrylic acid and a salt thereof is 70 to 100 mol % with respect to a total amount of monomer units in the crosslinked polymer,
• a value of non-pressurization DW after 30 seconds is 1.0 mL/g or more,
• a contact angle measured in a test performed in the order of i) and ii) below is 20 degrees or larger and 80 degrees or smaller, and
• a water retention capacity for a physiological saline solution is 35 to 60 g/g,
• i) a spherical liquid droplet, which corresponds to a diameter of 3.0±0.1 mm, of a 25% by mass saline solution is added dropwise at 25° C. onto a surface of a layer formed from the water-absorbing resin particles to bring the water-absorbing resin particles into contact with the liquid droplet, and
• ii) a contact angle of the liquid droplet is measured at a timing which is 30 seconds after the liquid droplet is brought into contact with the surface.
