PURPOSE:To automatically assemble a coil by an automatic inserting machine by providing stand-off units having fine holding pieces and press-bonding pieces opposed at the ends, and lead terminal units having lead terminal pieces extended at the other end sides of the stand-off units. CONSTITUTION:A striplike metal plate is used as a main frame 51, lead terminal pieces 52 disposed at the same interval as that of circuit patterns 41 at one edge side of the frame and stand-off units 55 of slightly broad width disposed at the ends of the terminal pieces are formed, and fine holding pieces 53 and lead press-bonding pieces 54 are provided at the ends of the stand-off units. Then, the circuit pattern 41 of a circuit substrate 4 is inserted between the pieces 53 and 54, positioned to be held, and the ends of the leads 31 of an inductor 1 contained in a through hole 42 are wired to the pieces 54. After a current is controlled while press-bonding it by the welding electrodes of an electric welder to connect the leads 31 to the pieces 52, excess leads 31 are removed, and the pattern 41 and the pieces 43 are soldered by a high melting point solder. Thus, the attachment of the inductor by an automatic mounting machine can be facilitated.
