Provided is a foam sheet that can raise an electrostatic capacitance at the time of compression, and hence can improve sensitivity when used for an electrostatic capacitance sensor. The foam sheet includes: a foam layer; and a pressure-sensitive adhesive layer arranged on at least one side of the foam layer, wherein the foam sheet has a dielectric constant increase amount Q-P at 10% compression of 0.2 (F/m) or more, where P (F/m) represents a dielectric constant of the foam sheet immediately after the foam sheet has been left at rest under conditions of a temperature of 23 C. and a humidity of 50% for 2 hours, and Q (F/m) represents a dielectric constant of the foam sheet at a time when the foam sheet is compressed by 10% immediately after being left at rest under the conditions of a temperature of 23 C. and a humidity of 50% for 2 hours.

Disclosed are a method for manufacturing a dissolvable slip and a dissolvable slip manufactured by same. The manufacturing method sequentially comprises the following steps: (1) mixing an adhesive with solid particles and dissolvable particles; (2) coating the mixture prepared in step (1) on the surface of a slip body; and (3) curing the mixture coated in step (2). The dissolvable slip manufactured according to the manufacturing method not only has a stronger anchoring force with a wellbore inner wall, but also can adjust the dissolution rate of the slip after the completion of fracturing to enable the slip to degrade within a preset time. Further, the dissolvable slip has a better abrasion resistance, is suitable for various temperature conditions, and can still work normally in a concentrated acid or a concentrated alkali environment.
