According to the reinforcing means to be bonded, a new reinforcing member needs to be added to the flexible electric board, or additional processing is required, so that the number of working steps increases, thereby complicating the manufacturing process. There is a problem that it becomes. In addition, there is a problem that the manufacturing cost increases.

Further, an increase in the number of working steps for performing additional processing or the like on the flexible electric board also leads to an increase in factors causing defective products at the time of manufacturing.

On the other hand, in a portion where it is not necessary to frequently attach / detach between the connection portion of the flexible electric board and the female connector of another electric board, in a normal state, both are always securely connected. In addition to the configuration in which the state is maintained, for example, when assembling equipment or performing repair work, etc., it is configured such that the attachment and detachment work of both can be easily performed as necessary. Need to be. In such a case, it is desirable that the connection portion between the connection portion of the flexible electric board and the female connector of another electric board has a simpler configuration and can be manufactured at low cost.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide a connection connecting portion having a connection pattern surface formed by arranging a plurality of conductor patterns. A flexible electrical board that is electrically connected to another electrical board by inserting the connect part into the insertion port of a female connector provided on another electrical board without adding a new member, and Reinforce the connect part while eliminating the need for processing work, etc.
