Then, the thread solder S is placed so that the top of the core C1 is traversed left and right. When the range Z including the entire thread solder S is heated, the thread solder S melts and the core wires C1 are soldered to the terminal portions 11a. That is, the terminal portions 11a are arranged in a straight line, so that batch soldering with one thread solder S is easy. Here, as shown in FIG. 12, the core wire C1 is soldered to the terminal portion 11a of the post 11 at a position sandwiched between the core wires C1 of the coaxial cables C adjacent to each other on the upper surface of the main body portion 12a.

For example, when the pitch of the terminal portions 11a is 0.3 mm, the pitch of the contact portions 11b is 0.6 mm. Therefore, since the left and right width dimensions of the contact portions 11b and 21b can be increased, the contact portions 11b and 21b can be easily formed. Further, since the terminal portions 11a are arranged in a straight line, only one thread solder S is used for batch soldering. Therefore, compared to the case where the terminal portions 11a are disposed in a staggered manner, for example, Batch soldering with S is easy.

  Instead of grounding the shell 13 via the holding bracket 23 as described above, as shown in FIG. 13, the terminal 13 a of the post 11 protrudes downward from the main body 13 a of the shell 13. For example, a contact piece 13f that is in contact with the contact piece 13f may be provided by cutting and raising, and the contact 21 corresponding to the post 11 with which the contact piece 13f comes into contact may be connected to the ground pattern of the printed wiring board P. If this configuration is adopted, there is no need to ground the shell 13 via the holding metal fitting 23. For this reason, for example, a connecting protrusion 23a for connecting the socket 2 to the shell 13 is provided on the housing 22, and the holding metal fitting 23 is not required. The score can be reduced.
