A production process for a breast pad and a breast pad. A water absorbing layer comprises a plurality of single water absorbing bodies (3) arranged in a plurality of vertically spaced columns. The single water absorbing bodies (3) in the same column are vertically symmetrically distributed. The single water absorbing bodies (3) in the adjacent columns arranged oppositely of the circular arc parts (3-1) are staggered. The single water absorbing bodies (3) in the adjacent columns arranged oppositely of the radial line parts (3-2) are arranged in a spaced manner and in a transversely symmetrical manner. The radial line parts (3-2) of the single water absorbing bodies (3) at two side edges of the water absorbing layer in the length extending direction are distributed toward the outer side. A water guiding layer above each single water absorbing body (3) is paved. Along the periphery of each single water absorbing body (3), the waterproof layers and the water guiding layers are welded by ultrasonic or connected by melting to obtain an integrated belt shaped base material (4). The belt shaped base material (4) is folded along the central lines of clearances of adjacent columns arranged oppositely of the radial line parts (3-2) and each pair of breast pad half bodies (2) are vertically symmetrically folded, the side edges of the radial line parts (3-2) of each pair of folded breast pad half bodies (2) are welded by ultrasonic or connected by melting, shearing or integrally blanking according to the preset size of the periphery of each single water absorbing body (3) is conducted, thereby obtaining a plurality of finished breast pad products.Linvention concerne un procédé de production pour un coussinet pour sein et un coussinet pour sein. Une couche dabsorption deau comprend une pluralité de corps absorbant leau (3) uniques agencés en une pluralité de colonnes espacées verticalement. Les corps dabsorption deau (3) uniques dans la même colonne sont réparties symétriquement
