A conductive member that forms a first coil pattern by electrically conducting the respective ends of the second group of front patterns and the second group of back patterns, and electrically conducting the respective ends of the second group of front patterns and the second group of back patterns. and a conductive member forming a second coil pattern, wherein the first coil pattern and the second coil pattern are flat so as to give the impression of a double coil pattern. (2) A noise removing device according to claim 1, wherein the conductive member connects the front pattern, the turn, and the back pattern through holes drilled in the substrate.

Claims

[Scope of utility model registration request]

(1) A plurality of linear patterns are printed on the first surface of the substrate, and these patterns form the front patterns forming the first group and the second group, and a plurality of line patterns are printed on the second surface of the substrate. A segmented pattern is printed and wired, and this pattern electrically connects the back patterns constituting the first group and the second group, and the respective ends of the front pattern of the first group and the back pattern of the first group. A conductive member that is electrically connected to form a first coil pattern is electrically connected to each end of the second group of front patterns and the second group of back patterns to form a second coil pattern. A nozzle removal device comprising a conductive member, wherein the first coil pattern and the second coil pattern form a double coil pattern.

(2) The noise removal coil according to claim 1, wherein the conductive member connects the front pattern and the back pattern through holes drilled in the substrate.

(3) The front pattern is printed and wired in parallel at a predetermined angle, and the back pattern is printed and wired in a direction that intersects the front pattern.Claim 1 of the Utility Model Registration Claim: The printed wiring board described.
