To suppress a discharge independence of a creepage distance while suppressing a cost increase of a material or a manufacturing.SOLUTION: A first conductive part A includes: a first front layer part A1; and first inner layer parts A2 to A4 constructing a layer different from the first front layer part A1 in an inner part of a substrate 49. A second conductive part B includes: a second front layer part B1 which is opposite to the first front layer part A1 with a creepage distance G; and second inner layer parts B2 to B4 constructing a layer different from the second front layer part B1 in the inner part of the substrate 49. In an electronic apparatus 40, any one projection structure having two projection structures of a first projection structure and a second projection structure indicated in the below is provided. The first projection structure is that each of the first inner layer parts A2 to A4 includes a conductive projection part ρ projected to a second conductive part side Db from the first front layer part A1. The second projection structure is that the second inner layer parts B2 to B4 include a conductive projection part projected to the first conductive part side Da from the second front layer part B1.SELECTED DRAWING: Figure 3 【課題】材料や製造のコストアップを抑えつつも、沿面距離に頼らずに放電を抑制する。【解決手段】第１導電部Ａは、第１表層部Ａ１と、基板４９の内部において第１表層部Ａ１とは異なる層を構成する第１内層部Ａ２～Ａ４とを有する。第２導電部Ｂは、第１表層部Ａ１と沿面距離Ｇをおいて対峙する第２表層部Ｂ１と、基板４９の内部において第２表層部Ｂ１とは異なる層を構成する第２内層部Ｂ２～Ｂ４とを有する。電子機器４０には、次に示す第１突出構成と第２突出構成との２つの突出構造のうちの少なくともいずれか一方の突出構成が設けられている。第１突出構成は、第１内層部Ａ２～Ａ４が、第１表層部Ａ１よりも第２導電部側Ｄｂに突出する導電突出部ρを有する構成である。第２突出構成は、第２内層部Ｂ２～Ｂ４が、第２表層部Ｂ１よりも第１導電部側Ｄａに突出する導電突出部を有する構成である。【選択図】図３
