PROBLEM TO BE SOLVED: To provide the installation structure of a substrate in an apparatus which can utilize the space of height direction of the substrate effectively, and which can select a component to be laid out on the substrate or the flexibility of laying out; and to provide an apparatus using the structure. SOLUTION: The installation structure of the substrate includes at least a first substrate and a second substrate, a reference flat plane as references of the height which fixes the first and second substrates, and a shield plate which gives a confinement to a distance from the first and second substrates to the shield plate. In this apparatus, the height of the first substrate from the reference flat plane is differentiated from the height from the reference flat plane of the second substrate and mounted. Thus, the limit of the distance from the first substrate by the shield plate is differentiated from the limit of the distance from the second substrate by the shield plate, and the space of the height direction of the first substrate can be utilized effectively.
