ELECTRODE MIXTURE SLURRY COATING DEVICE

An electrode mixture slurry coating device includes: a transport roller that transports a band-shaped base material; and a die head provided at a position opposed to the transport roller, and that discharges and applies an electrode mixture slurry to the base material being transported. The die head includes a fluid reservoir in which the electrode mixture slurry accumulates, a discharge port for discharging the electrode mixture slurry, and a fluid path that provides communication between the fluid reservoir and the discharge port. At least a portion, being adjacent to the fluid path, of the die head is formed of a first material having a coefficient of linear expansion of 4.0 ppm/K or less, and y
