WIRING BOARD |
| 摘要 |
Provided is a wiring board including an insulating board, and a wiring conductor formed on upper and lower surfaces of the insulating board, the wiring conductor including a differential line having two parallel strip-shaped conductors on the insulating board, the insulating board having a glass cloth and an insulating resin portion, in which the glass cloth is a bundle of glass fibers woven in a matrix, contains gaps, and has uneven surfaces, the insulating resin portion has flat surfaces and is formed on upper and lower surfaces of the glass cloth so as to fill the gaps and reduce the unevenness, and a difference in the dielectric constant between the glass cloth and the insulating resin portion is not larger than 0.5. |
