PROBLEM TO BE SOLVED: To provide an antistatic transparent resin plate which can demonstrate an outstanding antistatic property with little variation in surface resistivity despite improvement in transparency and see-through property by a pressing. SOLUTION: A pressed, clear antistatic transparent resin plate P having a transparent antistatic layer 2 on a surface of its thermoplastic clear resin substrate 1, wherein the antistatic layer contains 2 to 8 wt. % of a very thin, winding, entangled long carbon fiber and has a thickness of 0.05 to 0.50μm. The resin plate P has a total light transmission of 75% or more, a haze of 5% or lower, a surface resistivity of less than 10<SP>10</SP>Ω, and a variation between the average value X and the standard deviationσin the surface resistivity at X-3σand X+3σof two digits at maximum. The winding long fiber has a diameter of 3.5 to 100μm and an aspect ratio of 5 or more. COPYRIGHT: (C)2004,JPO&NCIPI
