    摘要: Provided is a silicone rubber molded body (1) including a conductive ink coating layer (3) that is disposed on a portion of the surface of the silicone rubber molded body (1). The conductive ink coating layer (3) contains a hydrolyzable organosilicon compound. Using the silicone rubber molded body with a saturated water absorption of 0.10 to 1.50% by mass and/or using a conductive ink containing water improves the affinity between the surface of the silicone rubber molded body (1) and the conductive ink coating layer (3). A residual ink area is an average of 20% or more and 100% or less after the conductive ink coating layer (3) is subjected to an abrasion test. With this configuration, the silicone rubber molded body has a high affinity between the silicone rubber and the conductive ink, good durability under continuous stress, and stability in long-term use. Further provided is a method for producing the silicone rubber molded body.

    摘要: A resin sheet for molding includes a base material sheet, and a surface layer provided on at least one surface of the base material sheet and including silicone, wherein the silicone content in the surface layer is 0.3 to 4.0 g/m2, and wherein the base material sheet is formed of a resin composition including 29 to 65 parts by mass of a Styrene-conjugated diene block copolymer (A), 25 to 60 parts by mass of a polystyrene resin (B), and 8 to 20 parts by mass of a high-impact polystyrene resin (C) (provided that a total amount of the component (A), the component (B), and the component (C) is 100 parts by mass). A carrier tape 100 is a molded body 16 of the resin sheet, wherein an accommodation portion 20 capable of accommodating an article is provided.
