PROBLEM TO BE SOLVED: To improve the detection accuracy of a load without interfering detection of the load by a strain gage. SOLUTION: A load sensor 5 for a vehicular seat comprises a long plate-like strain-generating body 9 extending substantially in a horizontal direction with a strain gage affixed thereto, an upper bracket 10 to connect one end side of the strain-generating body 9 to a cushion frame, and a lower bracket 11 to connect the other end side of the strain-generating body 9 to a seat rail, and detects the load of the vehicle seat based on the electric signal from the strain gage. A substantially horizontal seat face 18 for a frame is formed on an upper portion of the upper bracket 10, and a screw hole 18a for tightening the cushion frame is opened in the seat face 18 for the frame. A substantially perpendicular seat face 26 for a rail is formed on a side part of the lower bracket 11, and a screw hole 26c for tightening the seat rail is opened in the seat face 26 for the rail.
