Drip-proof sheet and electronic control unit

Abstract

A drip-proof sheet is attached to an electronic control device that includes a circuit board and a housing. The circuit board includes a wiring board on which a connector is mounted. The housing accommodates the circuit board with the connector exposed to an outside. The drip-proof sheet includes a fixation section, a drip-proof section, and a positioning section. The fixation section is secured to the electronic control device. The drip-proof section protrudes beyond a connector wall portion of the housing to reduce water ingress to the connector. The connector wall portion is a wall from which the connector is exposed to the outside. The positioning section is attached to the electronic control device by engagement that causes the fixation section and the drip-proof section to be positioned such that the fixation section is secured to the electronic control device and the drip-proof section protrudes beyond the connector wall portion.
