A mounting component for mounting an electronic part has a base that extends along a first surface of the electronic part, and a pair of left side and right side surface supporting sections that are extended from the base and bent along the right and left side surfaces of the electronic part, respectively. The pair of side surface supporting sections each have the screwing through hole at a position close to the one of the front end surface and the rear end surface. Further, a cushion member is interposed between the base and the electronic part, at a position close to the other of the front end surface and the rear end surface of the electronic part. The electronic part is screwed to the base through the surface supporting sections.
