PROBLEM TO BE SOLVED: To provide a sensor unit for measuring load weight, capable of improving accuracy in measuring load weight by minimizing change in output voltage due to temperature change of a sensor unit for measuring load weight attached to a loaded member expanding/shrinking due to loading of a weight such as a large truck, etc. SOLUTION: The sensor unit 11 for measuring load weight comprises a support 15 welded and attached to the loaded member expanding/shrinking due to loading of the weight, and a compression strain detecting sensor element 13 supported by the support 15 and generating output which changes with the expanding/shrinking due to the load change. The support 15 is formed of a high thermal conductive material. The support 15 and the loaded member are thermally bonded with a good thermal conductive member 31, such as copper or aluminum foil.
