Patent ID: 8289721

Claim:
An electronic unit comprising: a substrate including a first main surface and a second main surface opposite to the first main surface, on which an electronic component is mounted, and a support member that supports the substrate, wherein the support member includes a first support member and a second support member, with the substrate being sandwiched between the support members; the first support member has first side walls disposed on both ends, the first side walls each have a first side wall end portion, the first side wall end portions are formed substantially perpendicular to the first side walls, an end surface of each first side wall end portion comes into contact with the first main surface of the substrate, the second support member has second side walls disposed on both ends, the second side walls each have a second side wall end portion, the second side wall end portions are formed substantially perpendicular to the second side walls, an end surface of each second side wall end portion comes into contact with the second main surface of the substrate, the first side wall end portions, the substrate, and the second side wall end portions are fastened together, the first support member has a first contact member between the first side walls, and an end portion of the first contact member comes into contact with the first main surface of the substrate, the second support member has a second contact member between the second side walls, and an end portion of the second contact member comes into contact with the second main surface of the substrate, at least part of the area at which the first contact member is in contact with the substrate overlaps with a region at which the second contact member is in contact with the substrate, and the first support member and the second support member are configured substantially to reduce distortion of the substrate in a direction perpendicular to the first main surface and the second main surface.
