Disclosed is a hardwood bending device. The hardwood bending device is configured to form a hardwood piece of solid wood into a curved wooden piece for use as a part of furniture in the cabinetwork producing indoor furniture pieces, such as lighting fixtures, mirrors, and tables, or as a component of other finished products. The hardwood bending device utilizes a combination of wet-type and dry-type methods for bending a hardwood piece, and thus enables the mass production of wooden pieces with a uniform thickness as well as the production of products of uniform quality. Also, the hardwood bending device requires relatively low costs and equipment costs, and furthermore enables products with various shapes to be produced by using a single device, by replacing only a part of the device. According to an embodiment of the disclosure, the hardwood bending device comprises: a frame part having a structure in which a plurality of vertical frames and horizontal frames are interconnected to form a space therein; a support part provided on the upper surface of the frame part to fix a board-shaped wooden piece to be bent, so as to prevent the wooden piece from inadvertently departing from the frame part while being bent; and a forming part provided on the frame part spaced apart from the support part to press two side surfaces, in a thickness direction, of the wooden piece fixed to the support part, to bend the wooden piece to have a predetermined radius of curvature.
