<p>PROBLEM TO BE SOLVED: To obtain a transformer and its mounting structure, in which the state of mounting on a printed substrate can be stabilized with a relatively simple structure, and even if external force acts on it, influence on a wiring pattern containing a conductive land part can be reduced. SOLUTION: This transformer comprises a core part comprising a plurality of cores, a bobbin 3, and a coil part 2 containing a low-pressure coil 4a and a high pressure coil 4b in the bobbin 3. The bobbin 3 comprises at least a cylinder part 3a for arranging the low-pressure coil and high-pressure coil, a popularity of flange parts 3b to 3d formed at a distance in an appropriate part of the cylinder part, first and second terminal stands 3e, 3f formed in a both-end part of the cylinder part, and a plurality of pin terminals P1 to P7 disposed at a distance from each other in the first and second terminal stands, and one dot-like support part 3P is formed in a bobbin structure member which is positioned on a pin terminal side having a connection relation with the low pressure coil, and also two dot-like support parts 3S are formed in the bobbin structure member positioned on the pin terminal side, having a connection relation with the high-pressure coil.</p> |
