The layer 2 is formed of a thermally stable resin member and is insert- held by the part 3 (3a and 3b) consisting of electrically conductive members. The electrically conductive members are selected from material of a young's modulus higher than that of the thermally stable resin and joined to each other through a joining part 4. The part 4 is jointed to the other one with its projecting part projecting at an outer peripheral part and an inner peripheral part from one of the part 3.

摘要： PROBLEM TO BE SOLVED: To obtain a smooth grinding surface by enabling pressing force to satisfy a specific range in grinding processing of the specific number of grinding times of a blank after dress processing of a grinding wheel. SOLUTION: Pressurizing force (a grinding thickness) A (g/cm ) to an aluminium alloy plate (a blank) at grinding work time is increased within a range to satisfy a condition of [A1 (0.8+0.02×(B-1)) =A1 ] according to an increase in the number B of grinding times of the aluminium alloy plate (a work) after dress processing of a grinding wheel. Here, A1 is grinding pressure (g/cm ) of a first batch, and AB is grinding pressure (g/cm ) of a (B)th batch. Grinding force is enhanced by increasing the grinding pressure, and the degradation of productivity is prevented, and a grinding surface having excellent surface roughness is obtained.
