To provide a method for manufacturing a light-weight functional panel having a light weight, moisture regulating function, health advancing effect function, and excellent heat insulation, fireproofing and strength.

This method for manufacturing a light-weight functional panel comprises the steps of using a foam ceramic molding plate that fine ceramic hollow particles having a compression strength of 600kgf/cm2 or more, a bulk specific gravity of 0.3 to 0.5g/cm3 and a melting point of 1500°C or higher are point-connected by the melted ceramic or pottery composition as the front and rear surface material or front surface material of the panel, forming a core material in a honeycomb structure or a corrugated structure, and charging moisture regulator and tournaline in the structure space.
