<p>The circuit board (X4) according to this invention includes a board main body (1) having a width, and electronic parts (2). The board main body (1) includes first regions (1A) whose cross section crossing the board main body (1) in a width direction (W) has a relatively large area, and second regions (1B) whose cross section crossing the board main body (1) in the width direction (W) has a relatively small area. The electronic parts (2) are packaged in the first regions (1A) of the board main body (1). Preferably, the board main body (1) is formed with notches (1a, 1d, 1e) which partly reduce the width of the board main body (1). Preferably, the board main body (1) is formed with a hole (1b) extending through the board main body (1). Preferably, the board main body (1) is formed with a groove (1f) which partly reduces the thickness of the board main body (1).</p> |
