PURPOSE:To prevent harmful oozing-out of resin into the gaps between conductive leads by a method wherein the gaps between the leads are respectively made to bend into a labyrinthine form by projecting parts formed integrally with the lead on at least one side of the leads adjacent to one another of a large number of conductive leads. CONSTITUTION:Projecting parts 16 and 17 to intrude into gaps 38 between both outer lead parts 9 of outer lead parts 9 adjacent to each other in the state of almost a right angle to the gaps 38 are formed on the individual outer lead parts 9. The projecting parts 17 on the inside are spaced apart a boundary P and the parts between these projecting parts 17 and the boundary P are used as resin reservoir parts 18. When lead patterns 3 are formed en bloc, the projecting parts 16 and 17 are simultaneously formed integrally with the individual outer lead parts 9. Accordingly, the gaps 38 between the outer lead parts 9 are formed into bent parts 15 made to bend into a labyrinthine form by the projecting parts 16 and 17. Thereby, flowing-out resin 39 are stopped from oozing out lengthily in the directions of the points of the individual outer lead parts 9 in the gaps 38 between the outer lead parts 9. |
