The present invention relates to a composite board and a method for manufacturing the same: a composite board having a thickness of 2 mm or less formed by laminating a zirconia sintered body and a fiber-reinforced plastic in close contact with each other, and a zirconia sintered body and fibers The thickness ratio of the reinforced plastic (the thickness of the zirconia sintered body / the thickness of the fiber-reinforced plastic) is 0.01 to 1, and the apparent density of the composite plate is set to 4.3 g / cm 3 or less; the zirconia sintered body and the fiber-reinforced plastic are laminated A composite plate having a thickness of 2 mm or less, which is tightly fixed to each other, has a maximum value of a difference between unevenness on the surface of the zirconia sintered body of 50 μm or less per 1 cm 2 . |
