A memory card adapter includes a body having a set of contact pins. The set of contact pins include input pins and output pins implemented in a pin-to-pin structure. The input pins connect with pins of an inserted memory card and the output pins connect with an external socket. The body includes a bottom lead adapted to support the main body, and a top lead adapted to be combined with the bottom lead. The body includes a fixing substance adapted to combine with the contact pins. The body includes a conduction plate on a top surface or a bottom surface of the fixing substance, where the conduction plate is connected to at least one of the contact pins.
