To provide a manufacturing method of a novel low-profile connector, and to reduce the manufacturing cost, or the like.

In the manufacturing method of a low-profile connector, the connector body as upper and lower intermediate members of a low-profile connector is manufactured via a body molding step, a laser activation step, an electro-plating step, and a post-treatment step. The connector body is integrally made of connecting pin terminals and the connector body so that the cost for research and development of a manufacturing process and a mold manufacturing time can be reduced efficiently; and moreover the problem wherein metal connection pins of a conventional connector and upper and lower half shell bodes have to be processed separately that makes the manufacturing process for prolong manufacturing time complex can be solved, and further, the number of components can be efficiently reduced, a mold manufacturing cost and an inventory management stress can be relaxed, the cost for storing spaces can be reduced; and moreover, the manufacturing process is simple and can be automated to dispense with manual assembling and save on man-power cost for subsequent assemblings and promote mass production.
