A high-pass filter is also different from a low-pass filter shown in FIG. 2 and the like in that a capacitor AC6 is serially connected in a transmission path as shown in FIG. 23. One electrode (the conductor pattern MPt shown in FIG. 24) of the capacitor AC6 is connected to the transmitting circuit 202. Also, the other electrode (the conductor pattern MPr shown in FIG. 24) of the capacitor AC6 is connected to the receiving circuit 102.
Also, in the electronic device EDV9, a part of a noise filter NF6 which is a high-pass filter is formed of a conductor pattern of a wiring board 10 (see FIG. 22). More specifically, out of an inductor AL6, the capacitor AC6, and a resistor AR6 which constitute the noise filter NF6 shown in FIG. 23, each of the inductor AL6 and the capacitor AC6 is formed of a conductor pattern of the wiring board 10. Meanwhile, regarding the resistor AR6, a resistance value of a resistor component 40 which is a chip component (chip resistor) serves as a major part of the resistor AR6.
