The ear pad according to the present invention has a number of gathered sound-insulating walls (12) monolithically provided on an outer periphery of a basic body (11) made of an elastic material such as rubber, for instance, a silicon rubber or soft synthetic resins, for instance, polypropylene in a ring form with a prescribed space in the axial direction and made of the same material as that for the basic body. With this feature, the ear pad according to the present invention can provide softness and adaptability to be set in an auditory means without stimulating sensitive portions thereof.

What is claimed is: 1. An ear pad adapted to being inserted and detachably set in an auditory meatus and having a structure in which, on an outer peripheral surface of a hollow and cylindrical basic body made of an elastic material, a number of gathered sound-insulating walls made of the same material as the basic body are monolithically annularly provided on the basic body at predetermined intervals in the axial direction, the sound-insulating walls having a diameter which decreases toward the front of the pad, extending in a direction perpendicular to the center line of the basic body and having a wall thickness that reduces toward the outer periphery thereof, each wall contacting an inner wall of the auditory meatus with a peripheral edge bend thereof which extends toward the rear of the basic body such that several sealed spaces are formed for attenuating outside noise by bent walls which overlap and adjoin an adjacent wall at outer peripheral edges thereof when the ear pad is placed in the auditory meatus.
