"textContent": "A method of manufacturing a dry electrode sheet for a secondary battery includes providing a dry electrode composition comprising an electrode active material and a binder, a calendering operation of preparing an electrode sheet by passing the dry electrode composition through a calender roll including three or more rolls. The calendering operation includes a first electrode sheet manufacturing operation of manufacturing a first electrode sheet by injecting the dry electrode composition between two adjacent rolls spaced apart from each other by a first interval W1, and an electrode sheet manufacturing operation of manufacturing a dry electrode sheet by inserting the first electrode sheet between two adjacent rolls spaced apart from each other by a second interval W2. The first interval W1 and the second interval W2 have a compression rate of 0.10 or more and 0.65 or less, represented by the equation (1) compression rate=(W1−W2)/W1.",
