Abstract: A method and a apparatus for removing a micro component surely and leveling solder remaining on a substrate without imposing thermal damage to solder lands, the substrate and components on the periphery. A thermosetting adhesive (15) is provided on the surface (12a) of a micro component (12) opposite to the side of a substrate (11), and the distal end of a component holding pin (13) having cross-section area falling within the surface (12a) of the micro component (12) opposite to the side of the surface (11) is passed through the thermosetting adhesive (15) to abut against the surface (12a) of the micro component (12). Subsequently, solder (16) between the micro component (12) and the substrate (11) is heated to melt and the component holding pin (13) is moved in the direction receding from the substrate (11). Consequently, the micro component (12) is removed from the substrate (11).
