Summary:PROBLEM TO BE SOLVED: To provide an electronic apparatus capable of preventing occurrence of exfoliation in the junction surface of a sealing part, a cable and a joint interposed member, while ensuring durability thereof, and especially excellent in the environmental resistance.SOLUTION: An electronic apparatus 1A includes a case 10, a cable 30 pulled out from the case 10, a joint interposed member 40, a cylindrical clamp 50 for holding the cable 30, and a sealing part 60 filling the internal space defined by the case 10 and clamp 50. The cable 30 has a core wire 31, and a sheath 33 covering the core wire 31, and the core wire 31 is not covered with the sheath 33 but exposed at the end of the cable 30. The joint interposed member 40 is joined to the sheath 33 and sealing part 60. The sealing part 60 is composed of epoxy resin, and the joint interposed member 40 is composed of resin having a flexural modulus of 80-210 MPa, and the cable 30 has a hanging oblateness of 0.30-0.71.SELECTED DRAWING: Figure 3 【課題】封止部、ケーブルおよび接合介在部材の耐久性を確保しつつ、これらの接合面において剥離が発生することが防止できる耐環境性に特に優れた電子機器を提供する。【解決手段】電子機器1Aは、ケース10と、ケース10から引き出されたケーブル30と、接合介在部材40と、ケーブル30を保持する筒状のクランプ50と、ケース10およびクランプ50によって規定される内部の空間を充填する封止部60とを備える。ケーブル30は、芯線31と、芯線31を覆うシース33とを有し、芯線31は、ケーブル30の端部において、シース33によって覆われることなく露出する。接合介在部材40は、シース33および封止部60に接合する。封止部60は、エポキシ樹脂からなり、接合介在部材40は、曲げ弾性率が80MPa以上210MPa以下の樹脂にて構成され、ケーブル30は、吊下げ偏平率が0.30以上0.71以下のものにて構成される。【選択図】図3
