A multilayer printed circuit board is characterized in that circuit boards 1 and 2 and a circuit board 3 are laminated alternately to form a multilayer body using a simultaneous lamination method, the circuit boards 1 and 2 including a film-, thin plate-, or sheet-like insulating substrate 11 made of a thermosetting resin containing any one of epoxy resin, bismaleimide/triazine resin, and allylic polyphenylene ether resin as a major component, the circuit board 3 including a film-, thin plate-, or sheet-like insulating substrate 21 made of a thermoplastic resin containing a polyaryl ketone resin and amorphous polyether imide resin having a crystal-fusing peak temperature of 260° C. or more. By the present invention, it is possible to provide a multilayer printed circuit board which has small fusion or flow deformation at the time of simultaneous lamination, which does not have unevenness in positional precision in the lamination direction, which has no need for the processes to be readjusted, and which has high reliability in interlayer electrical connection.
