To provide a radome structure for an in-vehicle radar device that can reduce the manufacturing cost of a radome structure with a snow melting function, by simplifying a connection structure and a waterproof structure of a connection part which electrically connects a heater line and a power supply line of a radome to each other.SOLUTION: In the radome structure for an in-vehicle radar device, a planar heat generator 2 is deposited and fixed to a base material 1 of a radome, a local recessed part 3 is provided to protrude from the base material 1, a connector 4 which electrically connects an electrode of a heater line 21 of the planar heat generator 2 and a power supply line 5 for the planar heat generator 2 to each other is contained in the recessed part 3, and an insulating resin 6 is filled in the recessed part 3 to bury and seal the connector 4.SELECTED DRAWING: Figure 5 【課題】レドームのヒーター線と電力供給線を電気的に接続する接続部分の接続構造、防水構造を簡略化し、融雪機能を有するレドーム構造の製造コストを低減することができる車載レーダー装置用レドーム構造を提供する。【解決手段】レドームの基材１に面状発熱体２が積層して固着され、基材１から突出するようにして局所的な凹部３が設けられ、面状発熱体２のヒーター線２１の電極と面状発熱体２への電力供給線５を電気的に接続する接続体４が凹部３に収容され、接続体４を埋設して封止するように凹部３に絶縁樹脂６が充填されている車載レーダー装置用レドーム構造。【選択図】図５
