PROBLEM TO BE SOLVED: To provide a connected structure of woody boards allowing ready and reliable connection anytime and anywhere without tools. SOLUTION: The connected structure of woody boards is formed by connecting a top board 2, or the first woody board, and a side board, or the second woody board 20, together at right angles through a connection member 28. The top board 2 and the side board 20 have grooves 6 and 24, respectively, opening to the connection face, and the openings of the grooves 6 and 24 are formed in a bound form. The connection member 28 has one end part, 35 in Fig. 2, to be engaged in the groove 6 of the top board, and the other end part, 37 in Fig. 2, to be engaged in the groove 24 of the side board. The structure also has a protruding piece 41 which extends from the base of the one end part 35 and the other end part 37 in parallel with one face 9 of the top board and is brought in tight contact with corners of the top board 2 and the side board 20.
