<p>Provided is an electronic device (510; 510A) that can prevent water from entering from a closing member (70, 80; 80A) and a fitting section to which the closing member (70, 80; 80A) is fitted even under the use environment of the electronic device (510; 510A) in which thermal expansion and contraction can occur repeatedly. The electronic device (510; 510A) includes a main case (60; 60A) that is tubular, a closing member (70, 80; 80A) that closes an opening on one side of the main case (60; 60A), an electronic component that is arranged in the internal space enclosed by the main case (60; 60A) and the closing member (70, 80; 80A), and a resin section (120) that is formed by filling the main case (60; 60A) with a resin. The closing member (70, 80; 80A) has, over the entire circumference thereof that is opposite to the inner surface of the main case (60; 60A), an extension section (22; 22A; 22B; 22C; 22D; 22E; 22F) that forms a space between the closing member (70, 80; 80A) and the main case (60; 60A), the space being filled with a resin. The resin section (120) includes a first section that is provided in the space, and a second section other than the first section. The extension section (22; 22A; 22B; 22C; 22D; 22E; 22F) includes, over the entire circumference thereof, an engagement structure for preventing the resin section (120) of the first section from being shifted in the axial direction of the main case (60; 60A).</p> |
