The invention provides a method for compression-molding an electronic component and a die apparatus. A resin supply pre-plate (21a) is configured by forming an opening section (37) on a resin-storing section (22) by applying a die-releasing film (11) on a lower surface of a resin-storing plate (21) having the opening section (37) corresponding to a lower die cavity (5) so as to efficiently improve reliability of a resin quantity supplied into the lower cavity (5) at the time of supplying a granular resin (6) into the lower die cavity (5). A resin-dispersed plate (25) is formed by supplying the resin-storing section (22) with the granular resin (6) of a required quantity and flattening the resin (i.e., forming the resin in uniform thickness). Then, by placing the resin-dispersed plate (25) at a position of the lower die cavity (5) and pulling the die-releasing film (11) into the lower die cavity (5), the flattened granular resin (6) of a required quantity is dropped together with the die-releasing film (11) an
