The birefringence that results from the orientation of high molecular weight resins is cancelled out and still they are provided with heat resistance. To attain this object, the invention provides an optical resin material comprising a transparent high molecular weight resin and a fine inorganic substance which, as the linked chains in the high molecular weight resin are oriented under an external force, is oriented in the same direction as the linked chains and which has birefringence, the birefringence of said inorganic substance cancelling out the birefringence in orientation of the oriented high molecular weight resin. The invention also provides a process for producing the optical resin material, as well as optical components, an adhesive, substrates for a liquid-crystal device, and polarizing plates for the device.
