Abstract:
A method for manufacturing a coil device comprising a core including a reel and a pair of flanges provided at the ends of the reel, a terminal electrode disposed on each of the flanges of the core, and a wire wound around the reel of the core, thereby forming a coil, each end of the wire being connected to the terminal electrode, the method comprising the steps of:providing a conductive paste for forming the terminal electrodes at a desired thickness on a substantially planar surface of a conductive-paste supporting member; dipping the core in a conductive paste layer provided on the conductive-paste supporting member; and moving back and forth at least one of the conductive-paste supporting member and the core in a direction substantially parallel to an end surface of the flanges and the substantially planar surface of the conductive-paste supporting member provided with the conductive paste, thereby coating a bottom surface, side surfaces, and the end surface of the flanges with the conductive paste so that the upper edge of a conductive-paste coated area on the end surface of the flanges is disposed at a first level which is substantially the same height as the upper edges of conductive-paste coated areas on the side surfaces in the vicinity of the boundaries between the end surface and each side surface of the flanges and is disposed at a second level lower than the first level at an approximate center of the end surface of the flanges; and forming terminal electrodes by baking the conductive paste provided on the core.
