PROBLEM TO BE SOLVED: To enable a surface-mounting part to be reduced in size and thickness and improved in profitability, and its electrode to be improved in reliability. SOLUTION: A circuit part 2 is mounted on the one side of a board 1. The mounting surface of the board 1 is covered with molding resin 3, together with the circuit part 2. Terminal electrodes 9 are provided in the peripheral part of the board 1. The terminal electrodes 9 of the board 1 are formed in a manner, where a conductive material 10 filled up in through-holes 6 provided in the board 1 is cut off together with the molding resin 3, that covers the entire one side of the board 1.
