PROBLEM TO BE SOLVED: To provide coil parts whose influence on other parts is reduced, when mounting on a circuit board, and further the mounting strength to the circuit board is improved, and to provide an electronic apparatus. SOLUTION: The electronic apparatus 1 comprises the coil component 2 which is mounted on the circuit board 3 with a conductive paste. The coil part 2 comprises a drum core 4, and the drum core 4 has flanges 8A and 8B provided to both ends of the core. Winding wires 9 and 10 are wound around the cores of the drum core 4. The flanges 8A and 8B have terminal-forming regions 12 on both end sides. Two terminal fittings 13 and 14, electrically connected to both ends of the winding wires 9 and 10, are fixed to each terminal forming region 12, respectively. A grooved recess 16, having rectangular cross-sectional surface which opens in a mounting surface, is provided to the lower end of a region between the terminal-forming regions 12 in the flanges 8A and 8B. Consequently, progress of metal dendrite deposition due to ion migration is suppressed, at voltage application. COPYRIGHT: (C)2007,JPO&INPIT
