The invention relates to a lateral wall module for the body of a motor vehicle and to a method for its production. The lateral wall module extends to the rear in the longitudinal direction of the vehicle at least from an A-pillar as far as a rear wheel mounting, and has a lateral wall structure and also a lateral wall panel connected to the latter, the lateral wall structure, for its part, being constructed from an inner part and a wall part, which is fastened on the outside of the inner part and integrally reinforces the lateral wall module, and is at least partially designed in the sill region in such a manner that it complements the lateral wall panel there. In order to use the lateral wall module in a simple manner for a convertible or a coupe, it is proposed that the lateral wall panel is designed as a single-component pressed part which extends from the rear wheel mounting, firstly, over the lateral roof frame and the A-pillar as far as the front wall pillar and, secondly, over a sideboard as far as the box-section pillar, that the box-section pillar of the lateral wall module runs as far as the upper edge of the sideboard, and that the lateral wall panel and the lateral wall structure are designed in profile form in the manner of an open loop, the openings of the loops facing each other in the assembled state.
