To provide a load cell for simplifying a constitution, and accurately measuring a load.

The load cell 100 includes: a first both end fixed beam 110 having a region P0 for receiving the load, and a region to which a strain gauge unit 150 is attached; and a pair of second both end fixed beams 120, 130 disposed on both sides of the first both end fixed beam 110, and having regions R1, R2 for receiving a reaction force corresponding to the load. Both the ends of the first both end fixed beam 110 and both the ends of a pair of the second both end fixed beams 120, 130 are integrally fixed.
