PROBLEM TO BE SOLVED: To provide reinforcing glued laminated wood which is simple in structure, and contributes to improvement in strength against bending stress and strength against shearing stress. SOLUTION: According to the structure of the reinforcing glued laminated wood, two or more wooden plate members are laminated on each other, and grooves each having a semi-circular cross section for housing therein reinforcing steel rods, are formed in a laminated surface of each wooden plate member such that locations of the grooves match with each other, followed by boring shearing reinforcing bolt insertion holes through the wooden plate member in a plate thickness direction at regular intervals in a lengthwise direction of the wooden plate member. Then the reinforcing steel rod that is to be housed in the groove formed in the wooden plate member and has a plurality of protrusions formed on a surface thereof, is provided. The external diameter of the reinforcing steel rod is larger than an internal diameter of a groove having a circular cross section, that is secured by laminating the wooden plate members on each other. Then shearing reinforcing bolts are inserted into the respective shearing reinforcing bolt insertion holes to fasten the wooden plate members together, and the reinforcing steel rod is fixed to the wooden plate members laminated on each other in a manner biting the protrusions in the wooden plate members.
