PROBLEM TO BE SOLVED: To provide a reinforcing wooden material which can suppress an increase in cost while using prism-shaped wood as a principal material and securing necessary strength and which enables members to be connected together by simple field work using joint connection, nails and screws, a frame body for a sill, and a base-isolation sill structure. SOLUTION: The reinforcing wooden material 11 is formed by integrally covering a peripheral side surface of the prism-shaped wooden material 12 with a thin steel plate 22, and the frame body for the sill is formed by properly combining and connecting the wooden materials 11 together. A preferable base-isolation function also used for the sill can be imparted to the frame body for the sill by connection via a base-isolation means which is installed between the frame body and a concrete foundation formed in the ground direction of a site.
