Abstract: A light guide plate mold core (1) includes a main body (13) having a molding surface (12) and a plurality of concavities (13a) formed at the molding surface. The main body is made of a material whose thermal conductivity is limited in the range from 0.002 cal/cm.s.K. (calories/centimeter.second.Kelvin) to 0.009 cal/cm.s.K. The thermal conductivity of the material for the light guide plate mold core is less than that of stainless steel. Therefore the rate of spreading of heat in the light guide plate mold core is lower than that of a conventional light guide plate mold core, so that stresses within a formed light guide plate can be released more. Thus by using the light guide plate mold core, a light guide plate having a highly even bottom surface can be manufactured. A method for manufacturing the light guide plate mold core is also provided.
