It is made up of.
Among electronic control devices, electronic control devices of a type that are installed in, for example, an engine room require a waterproof structure because they may be exposed to water. A typical waterproof structure for an electronic control device is a structure in which gaps in the housing are sealed with a silicone adhesive or rubber packing.

ゴムパッキンを用いた電子制御装置として、上下に分かれた第１の筐体部と第２の筐体部で構成される筐体を用いて、電子回路基板を挟み込む構造が提案されている（例えば、特許文献１参照）。この電子制御装置において、第１の筐体部と第２の筐体部との間は、シール部材でシールされている。 As an electronic control device using rubber packing, a structure has been proposed in which an electronic circuit board is sandwiched between a casing consisting of a first casing part and a second casing part divided into upper and lower parts (for example, , see Patent Document 1). In this electronic control device, a seal member is used to seal between the first casing section and the second casing section.
