PURPOSE:To provide structure for mounting terminals of electronic part, which can solder terminals having sections relatively large in diameter to a printed board in a short time. CONSTITUTION:A small-diameter part 2b and a large-diameter part 2c are made, with the colar 2a at the middle as a boundary, at a terminal 2, and this terminal 2 is inserted into the base body 4 made of synthetic resin, and also a recess 7, where the small-diameter part 2b of the terminal 2b pierces, is made at the bottom of this base body 4, and the base body 4 is placed on a printed board 3. At this time, an air layer is demarcated by the recess 7 positioned between this printed board 3 and the base body 4. Hereby, the heat absorption at the small-diameter part 2b of the terminal 2 soldered to the conductive pattern of the printed board 3 is suppressed, and also the heat going from the small-diameter part 2b to the large-diameter part 2c is radiated by the air layer in the recess 7. |
