Metal-clad laminate and circuit board |
| abstract |
PROBLEM TO BE SOLVED: To provide a metal-clad laminate and a circuit board which can reduce transmission loss even in high frequency transmission and have excellent dimensional stability. SOLUTION: A metal-clad laminate 10 has a first metal layer M1, a first transmission loss suppressing layer BS1 in contact with one side thereof, a second metal layer M2, and a second transmission loss in contact with one side thereof. A plurality of resin layers interposed between the suppression layer BS2, the first transmission loss suppression layer BS1 and the second transmission loss suppression layer BS2 are provided. The resin laminate 20 has an intermediate transmission loss laminated between the first transmission loss suppressing layer BS1 and the second transmission loss suppressing layer BS2, at least two or more layers of the dimensional accuracy maintaining layer PL and the dimensional accuracy maintaining layer PL. It has an inhibitory layer BS3. In the metal-clad laminate 10, the total thickness of the dimensional accuracy maintaining layer PL is within the range of 25 to 60% of the total thickness of the resin laminate 20.
