    摘要： Degradation of post-sealing water-resistant performance is suppressed. An electronic device includes: a case member that includes a first end portion (310a) and a second end portion (310b); a flow control member (66) that includes a first opening (66a) and a second opening (66b); and a sealing resin (120) that is formed by solidification of a resin injected through a gate after the resin spreads into the case member by flowing in a first flow path between an inner surface (310k) of the case member and an outer surface (66n) of the flow control member (66) and a second flow path (66G) in the flow control member (66). Cross sectional shapes of the first flow path and the second flow path are determined such that the resin flowing in the first flow path reaches the second opening (66b) earlier than the resin flowing in the second flow path.

    摘要： A proximity sensor (100) capable of reducing the influence of periodic noise is provided. A proximity sensor (100) according to an embodiment of the disclosure detects a detection object (200) using a magnetic field, and includes a detection coil (11) for generating the magnetic field, an excitation circuit (20) for repeatedly supplying a pulsed excitation current to the detection coil (11), a detection circuit (30) for detecting the detection object (200) based on a voltage generated across both ends of the detection coil (11) during a predetermined period after the supply of the excitation current is cut off, and a control circuit (40) for controlling the excitation circuit (20) so that a timing of cutting off the supply of the excitation current to the detection coil (11) becomes aperiodic.
