PROBLEM TO BE SOLVED: To provide a sandwich type resin panel that can keep good appearance as an interior material produced by blow molding while suppressing increase of components necessary for other uses by effectively using the inside space for the other uses.SOLUTION: A resin sandwich panel 10 is composed of two resin surface material sheets 12 and a core material 13 sandwiched between the surface material sheets 12 and face-bonded to each of the surface material sheets 12. The core material 13 is made of a solid expanded resin of a predetermined expansion ratio, and has a long groove 16 with an opening on at least one surface 14. The opening of the long groove 16 is closed by the corresponding resin surface material sheet 12 to form a closed passage. The corresponding resin surface material sheet 12 has a through hole 18 in a thickness direction so as to communicate with the long groove 16.SELECTED DRAWING: Figure 2 【課題】内部スペースを他用途に有効に活用することにより、他用途に必要な部品点数の増大を抑制しつつ、ブロー成形により製造された内装材としての外観保持が可能なサンドイッチタイプの樹脂製パネルの提供。【解決手段】２枚の樹脂製表皮材シート１２と、両表皮材シート１２の間に挟み込まれる形態で両表皮材シート１２それぞれと面接着される芯材１３とを有する樹脂製樹脂製サンドイッチパネル１０であって、芯材１３は、中実状の所定発泡倍率を有する発泡樹脂製であり、芯材１３には、その少なくとも一方の表面１４に開口を形成する長溝１６が設けられ、長溝１６の開口が対応する樹脂製表皮材シート１２により閉鎖されることにより、密閉通路が形成され、対応する樹脂製表皮材シート１２には、長溝１６に連通するように厚み方向の貫通穴１８が設けられいる樹脂製サンドイッチパネル１０。【選択図】図２
