Provided is a vehicle body lower portion structure provided with a side collision sensor which can detect a collision earlier because of the improvement of the structure of the body. A first load transmission member (40) having a substantially Z-shaped vertical cross-section is disposed within the closed cross-section (30) of a rocker (12). A first joint section (40B) of the first load transmission member (40) is joined while being sandwiched between the upper flange (26D) of a rocker outer panel (26) and the upper flange (28D) of the rocker inner panel (28), and a second joint section (40C) is joined to the intermediate section, in the height direction, of the vertical wall section (26A) of the rocker outer panel (26). The body section (40A) obliquely connects the first joint section (40B) and the second joint section (40C) and is adapted to transmit a load toward the upper wall section (28B) of the rocker inner panel (28) through the shortest distance, the load being inputted into the rocker outer panel (26) during a side collision.
