The present invention relates to an automobile trunk board. A honey core (10) made of a plurality of fluted corrugated sheets is coupled to up and down glass mats (12, 14) to foam-form a main body (20) by using foam polyurethane (16, 18). Then a surface material (22) and a rear face material (24) are adhered, respectively, to an outer face of the main body (20) by using a hot melt (44, 46). At least one of the plurality of fluted corrugated sheets constituting the honey core (10) is made to a reinforced corrugated cardboard (30) having a curved part (38) constituted by double fluted corrugated sheets (40, 42) or a reinforced corrugated cardboard (32) constituted by a synthetic resin material. Accordingly, an automobile trunk board (26) which satisfies strength required in the industry is provided even without an increase in work time or excessive additional costs.
