PROBLEM TO BE SOLVED: To lessen a semiconductor device in manufacturing cost by a method wherein an internal thread is provided to an external lead-out terminal board so as to dispense with a conductor fixing nut and to save man-hours required to fit a nut in a package. SOLUTION: A part of an external lead-out terminal board 4 inside a package 1 and a mounting board 5 mounted with a semiconductor chip 2 are connected together with a connecting board 6, and the others of the terminal board 4 extending out of the package 1 is bent at a right angle so as to come into contact with the surface of the package 1, and a female thread 7 is provided to it. A blind hole 8 is bored in the package 1 corresponding to the internal thread 7, and a conductor 11 comprised in a main circuit and the external lead-out terminal board 4 are fixed together with a screw 9. |
