PROBLEM TO BE SOLVED: To provide a high frequency current suppressing electronic component which suppresses sufficiently a high frequency current and can prevent generation of electromagnetic interference, when the component is used at a high frequency. SOLUTION: This semiconductor integrated circuit element (IC) 1 is used in a high frequency band and operates at a high speed. High frequency current suppressing members 3 which attenuate high frequency currents flowing in terminals 2 themselves are installed to a prescribed number of the terminals 2. The suppressing members 3 are thin film magnetic substance whose thickness is in the range of 0.3-20μm and formed on the whole surface up to end portions including mounting parts to be mounted on a printed wiring circuit board 4 for mounting the IC 1 to the surfaces of the respective terminals 2, and connecting parts to conductive patterns 5 arranged on the board 4. By connecting tip portions with the conductive patterns 5 by using solder 6 when the IC 1 is mounted on the board 4, the vicinity of mounting parts exhibits conductivity in the used frequency band of at most several tens MHz. |
