wherein the first glass fiber layer comprises a resin and unidirectional glass fibers apart from each other,
wherein each of the unidirectional glass fibers extends in a first direction,
wherein a volume ratio of the resin included in the first glass fiber layer is about 10% or greater and about 30% or less,
wherein a volume ratio of the unidirectional glass fibers included in the first glass fiber layer is about 70% or more and about 90% or less,
wherein an elastic modulus of the first glass fiber layer in the first direction is greater than an elastic modulus of the first glass fiber layer in a second direction perpendicular to the first direction.
