PROBLEM TO BE SOLVED: To obtain a composite high frequency component that requires no matching circuit and is made small in size and to obtain a mobile communication unit using it. SOLUTION: The composite high frequency component 10 comprises a diplexer 2, 1st-3rd high frequency switches 3-5, and 1st and 2nd filters 6, 7. Then the diplexer 2 comprises 1st inductors L11, L12 and 1st capacitors C11-C15. Furthermore, the 1st-3rd high frequency switches 3-5 comprise 1st and 2nd diodes D1, D2, 2nd inductors L21-L23, and 2nd capacitors C21-C23. Moreover, the 1st and 2nd filters 6, 7 comprise a 3rd inductor L31 and 3rd capacitors C31, C32.
