PURPOSE: To provide the process for production of the metallic honeycomb structural body capable of improving the joining strength of the superposed parts of metallic plates to be joined and improving productivity.
CONSTITUTION: This process for production has a stage for superposing the same or different metallic plates 11 which are to be joined and at least one of which are corrugated plates, on each other by interposing an insert material 14 consisting of the low melting point having the m.p. lower than the m.p. of the metallic plates 11 or an amorphous metal via a superposed part 13 and a stage for seam welding the superposed parts 13 of the metallic plates 11 by means of roller electrodes 15 and an electrode 12. The honeycomb structural body 10 having many pieces of honeycomb holes is produced by successively repeating the stages.
