PROBLEM TO BE SOLVED: To provide a structural member for a wooden truss capable of effectively utilizing young thinnings, maintaining high size precision with less change by aging, and increasing yield strength. SOLUTION: A truss member 1 comprises a long log member 2, a steel rod member 3, and a junction device 4. A shaft center part of the log member is bored to form a vertical hole 25 to contain the steel rod member 3, and a socket engagement hole 26 opened at an end part of the log member 2 for containing a socket 6 for installing a sleeve nut 43, an installation thread hole 61L opened on the node side is provided in the socket 6, and a connection thread hole 63L to be engaged with a left-hand thread 3L for connection on the counter-node side to apply its tip to a bottom is formed. The truss member 1 reinforced by the steel rod member 3 achieves a large yield strength especially when tensile force or compression force is applied. A roof structure or a wall structure by three-dimensional trusses can thus be realized, thereby construction of such a large span wooden building as required for a gymnasium or a hall can be realized.
