Abstract: The insulating resin composition for electric power cable includes a polypropylene resin (A) that is a propylene-based polymer, and a styrene-based thermoplastic elastomer (B). The temperature characteristic curve of loss tangent tan ? obtained by dynamic viscoelasticity measurement at a frequency of 100 rad/s has a high-temperature-side temperature region in which the loss tangent tan ? is 0.1 or more and 0.4 or less, and a low-temperature-side temperature region in which the loss tangent tan ? is less than 0.1, and the highest temperature of the high-temperature-side temperature region is 240° C. or higher.

Abstract: A vehicular navigation device for presenting a navigation content by continuing a predetermined inputting operation for navigation till the last step even if the used state changes. The navigation device comprises a presentation unit (6) for presenting a navigation content, a manual input unit (3) for receiving a plurality of inputting operations, a speech input unit (4) for receiving a speech input operation substantially identical to that of the manual input unit (3), a database (5) stored with data necessary for navigation, and a control unit (2) for providing the navigation content to the presentation unit (6) by searching the database (5) according to the inputting operation from the manual input unit (3) or the speech input unit (4).
