Abstract
A noise filter includes a first capacitor and a second capacitor which are two line-to-line capacitors. Currents flowing through the first capacitor and the second capacitor are in directions opposite to each other, and meanwhile, currents flowing through a first connection wire and a second connection wire are in the same direction and parallel to each other. Accordingly, magnetic coupling is caused between the connection wires and the line-to-line capacitors. Thus, the residual inductance of a line-to-line capacitor itself is reduced, whereby an attenuation characteristic for normal mode noise is further improved.
