ABSTRACT:
There is provided a mounting construction which prevents leads of a semiconductor device from being short circuited when the semiconductor device is mounted on a mounting board so that mountability of the semiconductor device is improved. A plurality of outer leads extend from sides of a package of the semiconductor device. A mounting board has a surface on which a plurality of terminals to be electrically connected to the semiconductor device are provided. A mounting member is mounted on the mounting board separately from the semiconductor device. The semiconductor device is attached to the mounting member. The mounting member has a frame member forming a space in which the semiconductor device is placed. A first connecting lead has a first lead connecting portion and a first external connecting portion to be connected to a one of terminals provided on the mounting board. The first external connecting portion extends along a bottom surface of the frame member. A second connecting lead has a second lead connecting portion and a second external connecting portion to be connected to a one of the terminals provided on the mounting board. The second external connecting portion extends along a bottom surface of the frame member. The first external connecting portion and the second external connecting portion are arranged alternately with a predetermined distance apart from each other in a direction along an extending direction of the frame member.
