Adhesive tape

An adhesive tape comprising:

• a substrate made of a fluorine resin;
• and a silicone-based adhesive agent layer disposed on one surface of the substrate, wherein
• a surface of the silicone-based adhesive agent layer which is opposite to a substrate side surface of the layer forms an adhesive surface,
• the adhesive tape has a thickness of 50 μm or more,
• an adhesive strength of the adhesive surface to the other surface of the substrate after a friction test is 4.0 N/19 mm or more, and
• the friction test is performed according to a test method for coefficient of friction specified in JIS K7125:
• 1999, and performed in a state where:
• a contact surface, of a sliding piece used in the test method, brought into contact with a surface to be tested is covered with a single fiber cloth (cotton, for friction) specified in JIS L0803:
• 2011;
• the other surface of the substrate is defined as the surface to be tested;
• and
• the number of times of reciprocation is set to 10 times.
