PROBLEM TO BE SOLVED: To provide a winding electronic part having a high bond strength in the connecting section of a wire for a winding, and having the small dispersion of an inductance value; and to provide a manufacturing method for the winding electronic part. SOLUTION: The winding electronic part 2 has a drum core 4 with a core 4a winding the wire 10a on it so as to form a coil, and a pair of flanges 4b integrally formed to the core 4a and formed on both sides in the axial direction of the core 4a. Trapezoidal sectional-shaped recesses 30 for a connection are formed on both end faces in the axial direction of the drum core 4. End-section electrode films 20 are formed on the surfaces of the recesses 30 for the connection. Each connecting section 10b placed at both ends of the wire 10a wound on the core 4a is entered into each recess 30 for the connection, and crushed and connected at least at three places to the end-section electrode films 20.
