A pad comprising an approximate-quadrangular portion and approximate-arched portions attached to both lateral sides of the approximate-quadrangular portion and all the periphery of said pad is sealed with ultrasonic treatment wherein: when L represents the length of the approximate-quadrangular portion in the direction parallel to the lateral axis, S represents the length of the approximate-quadrangular portion in the direction parallel to the vertical axis and R represents a radius of said approximate-arched portion, following relations are satisfied: 0.5S&lE;L&lE;4S between L and S; 0.5S&lE;R<S between S and R, the production method and the adhesive bandage using said pad. The pad prevents peeling-off from four corners thereof and intrusion of water.
