Abstract
A transmission line including a conductor and a dielectric layer, wherein the dielectric layer includes plural bubbles and plural acicular nucleating agents, and when, based on observed lengths of the plurality of acicular nucleating agents observed in a cross section of the dielectric layer, the nucleating agents having lengths longer than a median value of the observed lengths are classified into a long nucleating agent group and the nucleating agents having lengths shorter than the median value of the observed lengths are classified into a short nucleating agent group, an average length of the nucleating agents in the long nucleating agent group is 3.5 times or less an average length of the nucleating agents in the short nucleating agent group.
