PROBLEM TO BE SOLVED: To provide a connection method capable of inhibiting a circuit board from being damaged by heat.SOLUTION: A connection method is used for electrically connecting a high-frequency signal line 10, which includes a dielectric element assembly 12 and an external terminal 16c provided on one main surface of the dielectric element assembly 12, with a circuit board 202b which includes a substrate body 207 and an external terminal 208c provided on one main surface of the substrate body 207. The external terminal 16c is placed in contact with the external terminal 208c. A voltage is applied to the external terminal 16c to weld the external terminal 16c to the external terminal 208c. |
