Claim:
1. A module comprising: a wiring board; a mounting electrode for component mounting, the mounting electrode being disposed on one principal surface of the wiring board; a component mounted on the one principal surface of the wiring board and solder-connected to the mounting electrode; a photosensitive resin covering the one principal surface of the wiring board with at least a connection surface of the mounting electrode exposed, the connection surface being connected to the component; and a sealing resin layer disposed on the one principal surface of the wiring board, the sealing resin layer covering the photosensitive resin and the component connected to the mounting electrode, wherein an edge of the photosensitive resin contacts a side of the mounting electrode and a portion of the photosensitive resin above the edge slopes away from the side of the mounting electrode to form a substantially V-shaped recess at a boundary between the mounting electrode and the photosensitive resin; and the recess is filled with resin of the sealing resin layer.
