PROBLEM TO BE SOLVED: To provide an inductance adjusting part for easily and correctly adjusting inductance at a part between a grounding electrode and a grounding part on a semi-conductor bare chip constituting a high frequency amplifier. SOLUTION: The high frequency amplifier using the semi-conductor bare chip includes a signal input side electrode 12 for inputting a high frequency signal, a signal output side electrode 13 for outputting the amplified high frequency signal, and the grounding electrode 14 for connection to the ground. The inductance adjuster 17 including conductive bodies 16La-16Lc, 16Ra-16Rc, which are calcined after coating a conductive paste by prescribed width through the use of an ink jet printer, is formed between the grounding electrode 14 and a grounding pattern 15.
