PROBLEM TO BE SOLVED: To provide an electronic circuit module which does not sacrifice fitting strength of a lower cover to a frame to which a fitting leg is provided, with no constraint on mounting position on a mother board. SOLUTION: The electronic circuit module 1 includes a frame 2 consisting of a metal plate arranged in square frame, comprising side boards 21-24, a circuit board 5 to which a high frequency circuit is provided, being supported by the frame 2 while being enclosed with the side boards 21-24, and a lower cover 3 of metal plate which is fitted to the lower end of the frame 2, to close the lower open end 2a. An L-shaped fitting leg 6 protruding downward by extending inward from the side board 21 and side board 22 is provided at a plurality of points of the lower end of the frame 2. An upward elastic piece 3c is provided over the entire circumference, at the perimeter of the lower cover 3. Protrusions 6b of the fitting legs 6 penetrate a through hole 3d provided to the lower cover 3 and soldered to a mother board 30. COPYRIGHT: (C)2009,JPO&INPIT
