摘要： A signal transmission cable includes a signal line, an insulation layer covering the signal line, and a shield layer covering the insulation layer. A first oxygen amount A1 on an outer peripheral surface of the insulation layer is 1.2 times or greater than a second oxygen amount A2 inside the insulation layer, or a contact angle on the outer peripheral surface the insulation layer is 130° or less, or an adhesion-wetting surface energy on the outer peripheral surface the insulation layer is 27 mJ/m2 or greater, or a first amount of a hydroxy group on the outer peripheral surface of the insulation layer is greater than a second amount of a hydroxy group inside the insulation layer.

摘要： A silicon nitride substrate including a first surface, and a second surface disposed opposite the first surface. One of the first surface or the second surface is a measurement surface. On the measurement surface, a value of an average full-width-at-half-maximum (FWHM) Cave is broader than 0 cm−1 and narrower than 5.32 cm−1 as measured by using a following measurement method. The measurement method of the average full-width-at-half-maximum (FWHM) Cave: one central point and four edge portions on the measurement surface are determined as measurement points; a Raman spectrum is measured at each of the measurement points; a full-width-at-half-maximum (FWHM) C of a spectral peak having the maximum strength within a range from 850 cm−1 or greater to 875 cm−1 or less is calculated in each Raman spectrum; and an average value of thus calculated full-width-at-half-maximum (FWHM)s C is the average full-width-at-half-maximum (FWHM) Cave.
