An electronic device is an electronic device that measures biological information. The electronic device includes a biological-information sensor section configured to measure the biological information and an armor case configured to house the biological-information sensor section. The armor case includes a case main body section and a rear lid section. One surface of the case main body section is integrally molded with a windshield and the other surface of the case main body section is formed of a transparent member in which an opening section is formed. The rear lid section is attached to the case main body section to close the opening section and at least a part of the rear lid section is formed of a transparent member.本發明提供一種可維持小型化、薄型化、及輕量化且提高防水性能之電子機器。電子機器係測定生物資訊者,其包括:生物資訊感測器部,其測定生物資訊;及外殼9,其收納生物資訊感測器部;外殼9包含外殼本體部10及後蓋部12,外殼本體部10之一面與風擋18一體地成形,另一面以形成有開口部20之透明構件構成,後蓋部12係以堵塞開口部20之方式而安裝於外殼本體部10,且至少一部分由透明構件而形成。9‧‧‧外殼10‧‧‧外殼本體部12‧‧‧後蓋部12-1‧‧‧後蓋部之內側12-2‧‧‧後蓋部之外側14‧‧‧保護罩18‧‧‧風擋20‧‧‧開口部22‧‧‧資料顯示窗部26‧‧‧操作按鈕28‧‧‧覆蓋板34‧‧‧導光控制部38‧‧‧螺母58‧‧‧螺栓70‧‧‧後蓋部襯墊72‧‧‧檢測窗74‧‧‧扣合部76‧‧‧翼狀部
