In a delay time measuring apparatus a sequence number, data length, and receiving time of a data packet transmitted from a source unit to a destination unit are stored in a storage section. In addition, an ACK number and receiving time of an ACK packet returned from the destination unit to the source unit are stored in the storage section. After that, a calculation section obtains an ACK packet an ACK number of which is equal to a value obtained by adding data length of a second data packet of two successive data packets transmitted without waiting for the ACK packet to a sequence number of the second data packet of the two successive data packets from the storage section. Then the calculation section calculates round trip time from receiving time of the second data packet of the two successive data packets and receiving time of the ACK packet obtained.

A capacitor includes a dielectric substrate and a large number of filamentous conductors formed to penetrate through the dielectric substrate in a thickness direction thereof. An electrode is connected to only respective one ends of a plurality of filamentous conductors constituting one of groups each composed of a plurality of filamentous conductors. The electrode is disposed in at least one position on each of both surfaces of the dielectric substrate, or in at least two positions on one of the surfaces. Further, an insulating layer is formed on each of both surfaces of the dielectric substrate so as to cover regions between the electrodes, and a conductor layer is formed on the corresponding insulating layer integrally with a desired number of electrodes.
