PROBLEM TO BE SOLVED: To provide a transmission line having flexibility and stability of characteristic impedance.SOLUTION: A transmission line 1 includes ground conductor patterns 11, 12, a signal line conductor 21, base material layers 31, 32, and a moisture absorption prevention layer 51. The ground conductor pattern 12 is formed to face the ground conductor pattern 11. The signal line conductor 21 is formed between the ground conductor pattern 11 and the ground conductor pattern 12. The base material layers 31, 32 are formed to fill between the ground conductor pattern 11 and the ground conductor pattern 12, and have flexibility. The moisture absorption prevention layer 51 covers the side faces of the base material layers 31, 32, and has flexibility and moisture resistance. The moisture absorption prevention layer 51 covers a predetermined range from the end face of the ground conductor pattern 11, and a predetermined range from the end face of the ground conductor pattern 12. |
