PROBLEM TO BE SOLVED: To provide a transparent composite sheet in which occurrence of surface ruggedness during its storage and its use is restrained, while keeping transparency. SOLUTION: The transparent composite sheet contains a cured resin (A), glass fiber cloth (B) and a glass filler (C). A refractive index difference between the glass fiber cloth (B) and the glass filler (C) is in the range of -0.01 to +0.01 at the same temperature in the wavelength of 589 nm. The glass filler (C) contains the glass filler having 1.5-10 aspect ratio and 4-15μm average minor axis diameter by≥30 vol.%. COPYRIGHT: (C)2011,JPO&INPIT |
