To provide a simple board support and electrical device which can be easily manufactured.

The board support is formed like a frame by connecting a support constituent member 4, in a horizontal position and a support constituent member 6 in a vertical position, wherein the constituent members 4 and 6 are connected by engagement between an engagement claw 46, provided projecting from the support constituent member 4 and an engagement hole 64 formed in the support constituent member 6. A circuit board 2 is attached to the board support attached to a display module 10. Since the board support is formed by combining the support constituent members 4 and 6, which can be manufactured by using a small-sized mold, it is not necessary to use a large-sized mold for manufacturing. Furthermore, since it is not necessary to fix the support constituent members 4 and 6 to each other with a screw for connecting them, the number of screws is reduced.
