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.

Transmission line

The present invention provides a layered product comprising a release layer that can be formed from an aqueous coating liquid, that is quickly released from the substrate when alkaline treatment is performed, and that has excellent water resistance. The layered product of the present invention is a layered product comprising a release layer on a substrate, the release layer comprising a granular carboxylic anhydride-modified olefin resin and a binding part containing an acid group-free thermoplastic resin, the carboxylic anhydride-modified olefin resin having an average particle size of 0.5 to 20 μm, the binding part having a thickness of 0.25 to 20 μm, and the release layer having an actual acid value of 100 mg KOH/mor more.
