PROBLEM TO BE SOLVED: To provide a small and inexpensive branching circuit board which is suitable for a mobile radio terminal for a single band and dual bands. SOLUTION: The board is provided with multilayer substrates 103, 104, 106 and 110, surface acoustic wave filters 101 and 102 different in pass bands on a transmission side and a reception side, a matching circuit 105 formed on the multilayer substrate 104, and a via conductor connecting the matching circuit 105 and the surface acoustic wave filters 101 and 102. The matching circuit 105 is formed in a bend shape at least at a lower part of mounting faces of the surface acoustic wave filters 101 and 102. COPYRIGHT: (C)2005,JPO&NCIPI
