To prevent an ACF (Anisotropic Conductive Film) tape from misalignment so as to achieve positioning with high accuracy.

This ACF sticking device 1 includes a first guide roller 17, a second guide roller 24, a pressing mechanism 26, and a pressure bonding tool 3. The first guide roller 17 holds one end of an ACF tape 110. The pressing mechanism 26 presses the one end of the ACF tape 110 against a display board 100. The second guide roller 24 holds the other end of the ACF tape 110. Further, the second guide roller 24 vertically presses down the ACT tape 110 the one end of which is pressed against the display board 100 by a first pressing mechanism 25, to bring the ACF tape 110 into contact with the display board 100. The pressure bonding tool 3 causes the ACF 109 of the ACF tape 110 pressed against the display board 100 to be pressure bonded against the display board 100.
