Connector, connector assembly, camera module, and assembly method

An assembly method for a connector assembly, the method comprising:

• an assembly step of attaching a first seal member in close contact with an outer circumferential face of a cylindrical external conductor extending in an axis direction, attaching a second seal member in close contact with an inner circumferential face of the external conductor, and inserting an internal conductor into the second seal member along the axis direction inside the external conductor, to thereby assemble a connector;
• a mounting step of installing the connector, with the first seal member and the second seal member attached thereto, on a surface of a substrate provided with solder;
• and
• a reflow soldering step of exposing the substrate, on which the connector with the first seal member and the second seal member attached thereto is installed, to a temperature environment where the solder melts,
• wherein the first seal member and the second seal member have heat resistance durable against a temperature in the reflow soldering step.
