PROBLEM TO BE SOLVED: To provide a precise and small-sized multiaxial force load cell capable of adopting a full bridge circuit, and reduced in an interference between component forces. SOLUTION: Two load cell half parts 11a, 11b are combined to be symmetric vertically, each plane load receiving part 13 having a screw part 12 is supported by inner end parts of four spoke columns 14 arranged crossedly in each of the load cell half parts 11a, 11b, an outer end part of the each spoke column 14 is connected to a cylindrical body 15 of a cylindrical shape in an outer circumference, and both end parts of the cylindrical body 15 are connected. The two plane load receiving part 13 are vertically provided independently, the four spoke columns 14 are respectively arranged vertically, total number of the spoke columns 14 gets to 8, four elements per the one spoke column 14 are bonded to a strain gage 16 of the 32 elements, and a size is compactified since the one element of strain gage 16 is enough to be bonded on one face in the spoke column 14 having a square cross section.
