PROBLEM TO BE SOLVED: To provide a wood structural member. SOLUTION: A wood structural member comprises: a first wood circular object having a first cooperative surface; a second wood circular object having second and third cooperative surfaces; and a third wood circular object having a fourth cooperative surface. The first operative surface is so formed as to cooperate with the second cooperative surface， the third operative surface is so formed as to cooperate with the fourth cooperative surface， and the first， second and third wood circular objects are fixed to one another， thereby forming a structurally integral unit. The first cooperative surface contacts the second cooperative surface， the third cooperative surface contacts the fourth cooperative surface， and the first， second and third wood circular objects are neary in parallel to one another. The first， second and third wood circular objects are fixed to one another by plural fasteners which are separated from one another along a length of the member. The plural fasteners comprise fasteners which are provided from a longitudinal axis of the structural member at both of an acute angle and an obtuse angle， and the fasteners so extend as to pass through the first， second and third wood circular objects.
