    摘要: A method of mounting an electronic part having a terminal portion on a board on which a circuit including a connection portion is formed. It includes a process of forming a conductive layer on the surface of the terminal portion; a process of forming, on the surface of the connection portion, a conductive layer having a melting point different from that of the conductive layer formed on the surface of the terminal portion; and a process of melting the conductive layer having a low melting point in such a state that the conductive layer of the terminal portion is contacted with the conductive layer of the connection portion, thereby fusing the conductive layer having a low melting point onto the conductive layer having a high melting point. Moreover, the method includes a process of forming a projecting portion made of a heat-resisting material on the surface of the electronic part around the terminal portion, and forming a conductive layer at least one surface of the connection portion or the terminal portion; and a process of electrically connecting the connection portion with the terminal portion and allowing the projecting portion to be contacted with the surface of the board.
