PROBLEM TO BE SOLVED: To provide a synthetic fiber airlaid composite sheet for food extraction not having influence on global environment, excellent in safety to human and a hygienic property, satisfying performances such as bag-making processability, heat stability, uniformity of formation and an extraction property without using a chemical agent such as a chemical binder or a paper-making auxiliary. SOLUTION: The synthetic fiber airlaid composite sheet is composed of at least two-layer fiber webs using only adhesive conjugate fiber as a raw material and composed of the fiber web of a heat-bonding conjugate fiber (A) in which a component on lower melting point side of either one fiber web is a melting point Am and the fiber web of a heat-bonding conjugate fiber (B) in which a component on low melting point side of the fiber web on the opposite surface is a melting point Bm, wherein the Am and the Bm satisfy the formula (1): Am≤Bm and the airlaid composite sheet is obtained by preparing these fiber webs into layers by an airlaid method and integrating bond between fibers by heating.
