Abstract
An elastomer molded body for a medical device includes an elastomer portion and a filler. The elastomer portion contains a crosslinked fluorine-based elastomer. The filler is formed from a plurality of particles each of which has aspect ratio of 5 or more and specific surface area of 3 m2/g or more and 10 m2/g or less. The aspect ratio is defined as a ratio of a dimension in a long axis direction thereof to a dimension in a short axis direction thereof. The filler has an uneven distribution in a surface layer part of the elastomer portion and is oriented in a direction along a surface of the elastomer molded body.
