摘要 |
On a circuit board (20) adapted to transmit a signal, a pulse transformer (12A) is provided on a path used for transmitting the signal of the circuit board (20). A shield member (15) is provided on the circuit board (20) for preventing noise, which is generated due to noise current flowing in a noise line pattern (16), from entering the pulse transformer (12A). The shield member (15) covers a surface portion (upper surface (26) and side surface (27)) of at least one pulse transformer that intersects concentric circles (30) whose central axis is axis A extending along the direction in which the noise current flows. |
