PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive which has good compatibility in compounded components, and thereby, has good storage stability, gives a low haze when the adhesive is processed into a pressure-sensitive tape, hardly causes changes in the adhesion strength when used in a high temperature and high humidity environment, and is suitable to be applied to an optical member. ! SOLUTION: The pressure-sensitive adhesive comprises a urethane-based polymer having a weight average molecular weight of 10000 to 200000 and a metal oxide having an average primary particle diameter of 5 to 100 nm, in which the metal oxide is included by 1 to 200 parts by weight with respect to 100 parts by weight of the urethane-based polymer. !
