The purpose of the present invention is to speed up delivery of a broadcast vehicle. In the present invention, an on-board mobile studio is provided with a lower framework the base material of which is iron, an upper framework the base material of which is aluminum, and brackets for connecting the lower framework and a vehicle. The on-board mobile studio is formed in a rectangular parallelepiped box shape which enables the studio to be loaded, as is, onto a vehicle as cargo. The on-board mobile studio, in a state where the equipment for a broadcast operation has been place therein, is delivered to a customer and is loaded onto a vehicle prepared by the customer. The lower framework is provided with: a planar upper-tier frame comprising a longitudinal beam and a lateral beam; a planar lower-tier frame comprising a longitudinal beam and a lateral beam; and a plurality of columns for connecting the upper-tier frame and the lower-tier frame. The brackets are connected to the upper-tier frame without interfering with the lower-tier frame. Lifting points are provided at the four corners of the roof of the upper framework. The lower framework can support the dead weight of the on-board mobile studio at such four corners.
