PROBLEM TO BE SOLVED: To provide a noise shield body which secures noise resistance and furthermore is inexpensive.SOLUTION: A metal housing 20 is constituted of one metal plate material 21 including a plane part 22 and at least three side face parts 23 connected to the plane part 22. The metal housing 20 is constituted by bending the plurality of side face parts 23 relatively to the plane part 22 by press bending. One sidewall part 24a includes, as an uneven portion, a triangular protrusion 26a in which a portion of the one sidewall part 24a protrudes in a triangular shape to the other sidewall part 24b side. The other sidewall part 24b includes, as an uneven portion, a triangular recess 26b in which a portion of the other sidewall part 24b is recessed in a triangular shape correspondingly to the triangular protrusion 26a. The triangular protrusion 26a and the triangular recess 26b are disposed oppositely so as to be fitted into each other at a fixed gap 25 therebetween.SELECTED DRAWING: Figure 2 【課題】耐ノイズ性を確保しつつ、安価なノイズシールド体を提供する。【解決手段】金属筐体２０は、平面部２２と、この平面部２２に接続された少なくとも３つの側面部２３と、を有する１枚の金属板材２１から構成されている。また、金属筐体２０は、複数の側面部２３が平面部２２に対してプレス曲げ加工によって折り曲げられたことにより構成されている。そして、一方の側壁部２４ａは、凹凸部として、当該一方の側壁部２４ａの一部が他方の側壁部２４ｂ側に三角形状に突出した三角凸部２６ａを有している。また、他方の側壁部２４ｂは、凹凸部として、当該他方の側壁部２４ｂの一部が三角凸部２６ａに対応して三角形状に凹んだ三角凹部２６ｂを有している。そして、三角凸部２６ａと三角凹部２６ｂとは一定の隙間２５を持って嵌合するように対向配置されている。【選択図】図２
