PROBLEM TO BE SOLVED: To enable voltage measurement at connection points between switching elements and a primary-side circuit by improving efficiency of adjustment while suppressing increase in size of a device and facility cost, in a DC/DC converter having a transformer.SOLUTION: A DC/DC converter has a structure in which an input filter circuit 14 connected to an input terminal and a full-bridge type switching circuit 15 having four switching elements 151 to 154 are provided on different substrates. A connection portion between a primary winding 12a of a transformer 12 and a circuit pattern 15c of the full-bridge type switching circuit 15 and a connection portion between the input filter circuit 14 and the circuit pattern 15c of the switching circuit 15 are electrode exposed portions 30a, 31a, and 40a where an inspection probe for measuring a voltage is contactable. |
