Abstract: Provided is a communication control device for controlling wireless communication of a mobile terminal, the device including: an acquisition unit that acquires reception sensitivity distribution information indicating reception sensitivity for each of a plurality of partial areas into which a communication area of a base station is divided, the base station communicating wirelessly with the mobile terminal, and acquires movement information with which a moving route of the mobile terminal is predictable; a prediction unit that predicts the moving route based on the movement information and predicts a communication speed of the mobile terminal on the predicted moving route based on the reception sensitivity distribution information; and a communication control unit that controls the wireless communication of the mobile terminal based on the predicted communication speed predicted by the prediction unit.

Abstract: The present invention has its object to provide an electrolyte anion which is high in decomposition temperature, in order to inhibit the electrolyte anion in the electrolyte solution for electrolytic capacitors from undergoing decarboxylation in the lead-free solder reflowing step to thereby prevent valve opening. The present invention uses an electrolyte solution comprising, as an electrolyte, the salt (A) composed of ammonium cation (a) and a polybasic carboxylic acid (b) anion, wherein the proton part charge of each carboxyl group in the polybasic carboxylic acid (b) as calculated by the quantum mechanics calculation software CAChe-based AM1 method is not higher than 0.243.
