The utility model relates to a novel solid wood section bar belonging to the field of the wooden product processing, especially to the fields of wooden floor and wooden furniture. The solid wood section bar provided in the utility model comprises a basic material layer and a compressed dense layer disposed on one side of the basic material layer, whereby the compressed dense layer and the basic material layer can be connected together to form an integrated body naturally through their own wood fiber. The above mentioned natural connection through their own wood fiber means that the compressed dense layer and the basic material layer are made of the same wood. One side of the wood can be compressed to form the dense layer and the basic material layer, which means that the bottom layer of the wood is not compressed, only the top surface is compressed. The utility model can be used for producing the wooden products such as floor or furniture.
