PURPOSE:To provide the surface material of a sanitary good which is difficult to break and has an excellent touch by a method wherein span bond nonwoven cloth is laminated on both surfaces of melt blow non-woven cloth, and further a pore is formed in a bonded region. CONSTITUTION:The surface material of a sanitary good is formed by a three- layer laminate of span bond non-woven cloth 1, a melt blow non-woven cloth 2, and a span bond top non-woven cloth 3. Bonded regions 4 having an arbitrary pattern is formed on the three-layer laminate. The bonded region 4 is a region in which the constituting fibers of each of the span bond non-woven cloth 1, the melt blow non-woven cloth 2, and the span bond top non-woven cloth 3 are softened or molten and cured in an integrally formed state. A pore 5 is formed in a part of the bonded region 4, and the diameter of the pore 5 is preferably approximate 0.01-1mm. In formation of the pore 5 in the bonded region 4, the heating temperature of a protrusion is increased or a press force is increased, and a film formed in the bonded region 4 may be molten. The tip of the protrusion is pointed and a film formed in the bonded region 4 may be pierced. |
