Claim 1:
2. The vaporizer for obtaining a gaseous material for film formation according to claim 1,
wherein, in a cross-section of the main part in a vertical direction with respect to a direction in which the mist of material flows,
when a direction in which the heat medium flows in a serpentine manner is taken as a horizontal direction, holes of the first flow paths are arranged in line in the horizontal direction, and hole rows are arranged to form layers in a vertical direction,
the second flow paths are present between vertically adjacent hole row layers, respectively, the second flow paths are not connected to the first flow paths, and the second flow paths vertically meander so as to avoid the holes of the first flow paths in the hole row layers between which the second flow paths are sandwiched in the vertical direction, respectively.
