A load sensor-equipped operation apparatus. An operational member is movably operated. A reaction force member receives an operating force from the operational member, and a reaction force corresponding to the operation force. At least one pivotal connecting portion is interposed between the operational member and the reaction force member, pivotably connecting a pair of a first member and a second member relative to each other to transmit the operating force. A load sensor, which electrically detects the operating force, includes a shaft-like member, a main body member disposed to be relatively displaced in a direction perpendicular to an axis of the shaft-like member, a deformable member bridging the shaft-like member and the main body member, and a strain detecting element secured to the deformable member, which detects deformation of the deformable member. A transmittal link connects the first member to one of the shaft-like member and the main body.
