High-frequency signal line and electronic device

A high-frequency signal line comprising:

• an element assembly including a plurality of flexible insulator layers;
• a linear signal line provided in or on the element assembly;
• a first ground conductor provided in or on the element assembly, so as to be opposed to the signal line not in a first section including a portion of the signal line but in a second section adjacent to the first section;
• and
• a second ground conductor provided along the signal line in the first section on the insulator layer on which the signal line is provided;
• wherein
• the second ground conductor is not opposed at least in part to the first ground conductor in the first section.

An electronic device comprising:

• a housing;
• and
• a high-frequency signal line accommodated in the housing;
• wherein
• the high-frequency signal line includes:
• an element assembly including a plurality of flexible insulator layers;
