Particle beam device, calculation device for adjusting transport path, and method for manufacturing particle beam device capable of adjusting a transport path in a short time with a small number of trials

The present invention aims to provide a particle beam device capable of adjusting a transport path in a short time with a small number of trials, a calculation device for adjusting a transport path, and a method for manufacturing a particle beam device. In a method for manufacturing a particle beam therapy device (1), candidate values of parameters of a beam adjustment unit (20) are searched by adjusting the beam size and beam position through an optimization means. In this way, by searching for candidate points in the parameters of the beam adjustment unit (20) through the optimization means, optimal parameters for achieving the desired beam size and beam position can be obtained with a small number of trials. Accordingly, by using the searched candidate values in the parameters to adjust the beam adjustment unit (20), the transport path can be adjusted in a short time with a small number of trials. In addition, the manufacturing time of the particle beam therapy device (1) can be shortened, and the burden o
