A module includes a wiring board; a component mounted on the wiring board; a columnar conductor for external connection, the columnar conductor being connected at one end thereof to the wiring board; and a resin layer disposed on the wiring board and configured to cover the columnar conductor and the component, with an end face of the columnar conductor exposed from a surface of the resin layer, the end face being at the other end of the columnar conductor. A gap to be filled with solder is formed between the resin layer and a periphery of an end portion of the columnar conductor, the end portion being at the other end of the columnar conductor. |
