The authors developed seismic retrofit wall consisted by CFRP (Carbon Fiber Reinfoced Plastic) shear units which have high strength performance. The shape of the CFRP shear unit is a hollow box, the outlines of which are 80mm or 100mm in depth, 300mm in height and 900mm in horizontal length. The unit has CFRP skin plates outside which is reinforced carbon fibers in ±45 degree from horizontal direction. An earthquake-resistance wall is built up by means of bonding ench units th epoxy resin adhesive. Shear tests for the shear units and the joints were carried out The final failure mode of the unit was buckling and the average buckling load was 723kN. The adhesive strength for the unit was 8.8N/mm^2. On the other hand, shear tests for the4 types of the shear walls which were constructed by the units were carried out. The maximum shear load for the shear wall was 849 kN/m. This value is sufficient foreaithquake-resistance shear wall.
