Wiring board and wiring board module

A wiring board comprising:

• a board body on which components are to be mounted;
• and
• a plurality of mounting lands provided on the board body at locations corresponding to terminals of the components to be mounted;
• wherein
• at least one of the mounting lands is divided into a plurality of land pieces;
• and
• a swell correcting pattern is provided in a region on a surface of the board body where no mounting lands are provided and is arranged to intentionally generate swells such that an amount of swell in the region in which no mounting lands are provided is substantially the same as that in a region in which the mounting lands are provided.

A wiring board comprising:

• a board body on which components are to be mounted;
• and
• a plurality of mounting lands provided on the board body;
• wherein
• at least one of the mounting lands is defined by a plurality of adjacent land pieces that are to be electrically connected via a terminal of one of the components to be mounted and that are to thereby function as a mounting land for the terminal;
• at least another one of the mounting lands is defined by a single land;
• an area ratio A/a between a largest area A of areas of the land pieces of the at least one of the mounting lands and a smallest area a of the single land of the at least another one of the mounting lands is about 3 or less;
• and
• a swell correcting pattern is provided in a region on the surface of the board body where no mounting lands are provided.
