- a constituent layer having a thickness of 40 / im or less is obtained without including a reinforcing member such as a glass cloth, and a thin laminated substrate can be provided.
- the laminated substrate of the present invention can be manufactured by a method as shown in FIGS.
- a copper (Cu) foil 102 as a conductor layer having a predetermined thickness is laminated and adhered to a transfer film 103 having a predetermined thickness.
- a sheet for protecting the adhesive surface of the transfer film may be pasted, and this may be removed when bonding the Cu foil.
- the adhesive strength of the transfer film is preferably 7 N / 20 mm or less, and more preferably 3. to 7. ON / 20 mm.
- the adhesive strength is 3.7 N / 20 mm or less, the conductor layer is peeled off in the etching process or the like, and the etchant easily enters between the layers.
- the adhesive strength is larger than the above range, the transfer film becomes difficult to peel off from the prepreg.
- step B the copper foil 102 is patterned into a desired pattern shape.

- the processing temperature is too high, the curing of the prepreg will proceed too much, and the resin flow will be poor when the prepreg itself is multi-layered, and the adhesiveness will be reduced. Also, if the processing temperature is too low, it becomes difficult to transfer the pattern. If the pressure is too high, the transfer film will stick to the pre-preda and cannot be peeled off. If the pressure is too low, the resin will flow between the pattern and the film, causing problems in subsequent steps such as plating not attaching, surface roughening and etching not possible.
