A titanate whisker characterized by high heat resistance, excellent chemical resistance and reinforcing performance and low thermal conductivity. The whisker is represented by the general formula: AIvAIIwMIIxMIIIyTi3-zO16, wherein A1 is at least one member selected from among alkali metals; AII is Ba; MII is at least one member selected from among Mg, Co, Ni, Zn, Cu and Mn; MIII is at least one member selected from among Al, Sc, Cr, Fe and Ga; and v, w, x, y and z are real numbers satisfying the relationships: 0,5≤2x+y≤2,5, 2x+y=v+2w and z=x+y. |
