PROBLEM TO BE SOLVED: To provide a drainage structure capable of appropriately draining water entering through a gap between a cover and a block.SOLUTION: A drainage structure 100 comprises: a block 5 for holding an electronic component at the top; and a cover 4 that has inner wall portions 43b, 44b opposed to the side wall portions 5c, 5d of the block and integrally covers the electronic component and the block from above. At least one wall portion of the side wall portion and the inner wall portion comprises: upper confronting surfaces 58c and 58d opposed to the other wall portion at the first intervals L1 and L3 at which water cannot rise due to the capillary phenomenon; and a raised portion 64 protruding from the lower portion of the upper facing surface toward the other wall portion. The raised portion includes a lower opposed surface 64a opposed to the other wall portion at second intervals L2 and L4 narrower than the first interval, a stepped surface 64b connecting the lower facing surface and the upper facing surface and facing upward, and a passage portion communicating a space above the raised portion and a space below the raised portion and connected to the stepped surface. The stepped surface is inclined toward the passage portion.SELECTED DRAWING: Figure 8

    【課題】カバーとブロックとの隙間から入り込んだ水を適切に排水できる排水構造を提供する。【解決手段】排水構造100は、上部に電子部品を保持するブロック5と、ブロックの側壁部5c,5dと対向する内壁部43b,44bを有し、電子部品およびブロックを上方から一体に覆うカバー4と、を備え、側壁部および内壁部の少なくとも何れか一方の壁部は、毛細管現象による水の上昇が不能な第一の間隔L1,L3で他方の壁部と対向する上側対向面58c,58dと、上側対向面の下部から他方の壁部に向けて隆起した隆起部64とを備え、隆起部は、第一の間隔よりも狭い第二の間隔L2,L4で他方の壁部と対向する下側対向面64aと、下側対向面と上側対向面とをつなぎ、かつ上方を向く段差面64bと、隆起部よりも上方の空間と隆起部よりも下方の空間とを連通し、かつ段差面につながった通路部とを有し、段差面は、通路部に向けて傾斜している。【選択図】図8
