An information processing device is disclosed. The information processing device includes a first chassis and a second chassis that are connected rotatably via a hinge, and includes a connector to connect the first chassis to the hinge. The first chassis includes a laminated part having a lamination of a set of fiber-reinforced plastic layers in each of which resin is reinforced by fibers arranged in a predetermined direction. The connector is attached and fixed to a recess in the laminated part, with the recess having a shape corresponding an outer shape of the connector. Directly attached to the connector, one of the fiber-reinforced plastic layers making up a bottom of the recess and is a layer in which fibers are arranged in a direction orthogonal to a rotary axis of the hinge.
