  "textContent": "Ear portions are formed on a ribbon-shaped strip to make the thickness of an inner liner uniform. A strip for an inner liner of the present invention is a strip of a thermoplastic elastomer composition to be wound spirally on a cylindrical drum to form an inner liner for a tire having a shape close to a finished sectional shape. The strip is composed of a layer stack of (A) a first layer made of a thermoplastic elastomer composition containing 0.1 part by mass to 50 parts by mass of an organic derivative of clay mineral relative to 100 parts by mass of a styrene-isobutylene-styrene triblock copolymer, and (B) a second layer made of a thermoplastic elastomer composition containing at least one of a styrene-isoprene-styrene triblock copolymer and a styrene-isobutylene diblock copolymer. The strip has a strip main body and ear portions disposed on opposite sides thereof. The strip main body has a thickness (T1) of 0.05 mm to 1.0 mm. The ear portions have a thickness (T2) thinner than the thickness (T1) of the strip main body and a width (W2) of 0.5 mm to 5.0 mm.",
