Zusammenfassung:	To provide a hub type blade which enables efficient and stable manufacture of a hub type blade having high accuracy.SOLUTION: A hub type blade includes: a hub which is rotatably formed around an axis line and has a blade fitting surface formed on one side in the axis line; a blade body arranged on the blade fitting surface; and a connection part which is arranged between the hub and the blade body and allows the blade body to be mounted on and connected to the hub. The connection part is composed of a double-sided adhesive tape having adhesiveness on both surfaces positioned on the hub side and the blade body side, and the blade fitting surface is formed so as to have surface roughness Rmax of 0-20 μm.SELECTED DRAWING: Figure 2 【課題】高精度なハブ型ブレードを効率的かつ安定して製造することが可能なハブ型ブレードを提供すること。【解決手段】本発明の一態様に係るハブ型ブレードは、軸線回りに回転可能に形成され前記軸線方向の一方側にブレード取付面が形成されたハブと、前記ブレード取付面に配置されたブレード本体と、前記ハブと前記ブレード本体の間に配置され前記ハブに前記ブレード本体を装着して接続する接続部と、を備え、前記接続部は、前記ハブ側と前記ブレード本体側に位置される両面に粘着性を有する両面粘着テープにより構成されており、前記ブレード取付面が、表面粗さＲｍａｘが０〜２０μｍに形成されていることを特徴とする。【選択図】図２
