An object is to provide a molded product, which has dielectric properties that the conventional liquid crystal polyester resin has not realized, and simultaneously which keeps a heat resistance such as solder reflow of a liquid crystal polyester, and which is used in information and telecommunications equipment employed in high frequency band regions such as microwaves and millimeter waves. A molded product of a wholly aromatic liquid crystal polyester resin composition which has a dielectric constant of 3.0 or less and a dielectric dissipation factor of 0.04 or less and which is obtained by an injection molding of a composition comprising 90 to 45 percent by weight of the wholly aromatic liquid crystal polyester having a melting point of 320° C. or more, 10 to 40 percent by weight of an inorganic spherical hollow material having an aspect ratio of 2 or less, and 0 to 15 percent by weight (100 percent by weight in total) of an inorganic filler having an aspect ratio of 4 or more. The molded product of the present invention has dielectric properties suitable for information and telecommunications equipment, and is excellent in solder heat resistance, processability, and dimensional stability so that the molded product is advantageous as a substrate material for use in information and telecommunications equipment such as a cellular mobile phone and as a fixing or a holding member of a transmitter-receiver element.
