To provide a cylindrical grinding wheel which makes a cylindrical body an empty can-like cylindrical body which has a thin wall with a low rigidity and of which one side face opens, forms plural holes in an outer peripheral surface thereof and electrically deposits super abrasive grains thereto, and a method for manufacture of the same.SOLUTION: An empty can type cylindrical grinding wheel K1 makes a cylindrical body an empty can-like cylindrical body 10 which has a thin wall with a low rigidity and of which one side face opens, has a fitting hole S1 for a rotary shaft S on a side wall 10B on a side opposite to the empty can-like cylindrical body. Countless number of small holes h or slit holes L are provided in an outer peripheral surface 10A of the empty can-like cylindrical body, and further, diamond, CBN electrodeposition abrasive grains or WA, GC abrasive grains are deposited onto the outer peripheral surface 10A of the empty can-like cylindrical body.SELECTED DRAWING: Figure 3 【課題】円筒体を剛性の低い薄肉で片側面が開放した空き缶状の円筒体とし、この外周面に多数の孔を開けるとともに超砥粒を電着させた円筒研削砥石とこの製造法に係わる。【解決手段】円筒体を剛性の低い薄肉で片側面が開放した空き缶状円筒体１０となし、上記空き缶状円筒体の反対側の側壁１０Ｂに回転軸Ｓとの取付穴Ｓ１を有し、上記空き缶状円筒体の外周面１０Ａには無数の小孔ｈ又はスリット孔Ｌを設け、更に、上記空き缶状円筒体の外周面１０Ａに、ダイヤ，ＣＢＮ電着砥粒又はＷＡ、ＧＣ砥粒を固着させた空き缶型円筒研削砥石Ｋ１である。【選択図】図３
