PROBLEM TO BE SOLVED: To provide a car load measuring sensor unit of improved reliability for the detection precision of a load sensor by providing a sensor holder wherein a heat occurring at welding to a member which is to be loaded is reduced. SOLUTION: A car load measuring sensor unit 28 is attached to a to-be- loaded member 21 of a car, for measuring a car's load, which is relatively displaced under such load as applied on the car, with a sensing element (load sensor) 29 and a base assembly (sensor holder) 30 provided. At the base assembly (sensor holder) 30, the end part of each fitting part 39 as a welding part welded to the to-be-loaded member 21 and a through hole 40 for releasing weld heat are formed. The through hole 40 is formed between the end part as the welding part and the fitting part of the sensing element (load sensor) 29.
