PROBLEM TO BE SOLVED: To provide a louver blade and a louver, capable of reducing a wind speed by eliminating a difference in the passing air volume between an end part and an intermediate part of the louver blade. SOLUTION: This louver blade 1 has an inclined face 3 becoming high toward the inside from the outside, and is a polyhedron. In the louver blade 1, a straightening body 28 is placed in both end parts of the louver blade, the body 28 having a surface 28(a) forming a vertical plane to the outside of the louver blade, a surface 28(d) forming a surface substantially parallel to an inclination of an outside inclined face 3B1, a surface 28(b) forming an inclined face narrowing downward and inward along the outside inclined faces 3B1 and 3B2, and narrowing toward the outside of the louver blade, and a surface 28(c) forming an inclined face expanding toward the outside of the louver blade.
