PROBLEM TO BE SOLVED: To provide a connected type washer for sheet execution of waterproofing work which is excellent in handling property and stability in feeding. SOLUTION: A plurality of dish parts 3 is molded to be arranged in on line on a high density polyethylene sheet by means of a press die, and portion other than the dish parts 3, flange parts 4 around the dish part 3, and connection tab parts 5 which connect the dish parts are removed by blanking thereby forming connected type washer 1 of a single belt shape. Since each of the connection tab parts 5 has an appropriate hardness, handling property is excellent compared with a connected type washer in which single washers are connected to each other by a tape, and a fluctuation of an array pitch of the washer due to the stretched tape does not occur, thereby reducing probability of a feeding failure.
