<p>PROBLEM TO BE SOLVED: To provide a transformer which has a high pressure rise rate and a high conversion efficiency, even if it is made thinner smaller and moreover has a structure which can be simplified. SOLUTION: A spiral or meandering transmission line 41 composed of a conductor is interposed between a pair of cores 4, 4 having a dielectric property and magnetism. Ground conductors 42, 42 are formed outside the pair of cores 4, 4. Trenches 7 for preventing magnetic flux interlinked to the transmission line 41 are formed in the cores between the transmission lines 41.</p> |
